NOTES: With pre-attenuator set to AUTO, some discontinuity of the GAIN may occur at 20 db and 40 db, therefore, linearity is not guaranteed. The same GAIN value with different ATT values may show different noise level. The best signal-to-noise ratio will be achieved with ATT set to AUTO, i.e. the best combination of gain and attenuator Selection ATT value other than AUTO will change available GAIN range as follows: - AUTO GAIN range 0 111 db; - 0 db GAIN range 0 71 db; - -20 db GAIN range 20 91 db; - -40 db GAIN range 40 111 db. 4.2.7 DAMP Adjustment of the receiver damping (impedance): - 42 Ohms; - 51 Ohms; - 180 Ohms; - 1000 Ohms. 4.2.8 PRF Adjustment of the Pulse Repetition Frequency in steps: 10, 20, 50, 100, 200, 500, 1000, 2000, 2500, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 11000, 12000, 13000, 14000, 15000, 16000, 17000, 18000, 19000, 20000 Hz. Maximum PRF is limited depending on the actual time base RANGE. Therefore, if the next higher PRF value is too high for the actual RANGE value, then >--<<?? appears instead of the PRF value. Nevertheless, if the right side button had been depressed once more, then the PRF increases to the next higher value, and at the same time, the RANGE value automatically decreases accordingly. DRC Srl 2012 30/102

There are automatic PRF modes available for 200, 100, 50, 20 Hz (indicated by AUTO next to the PRF value), i.e. maximum possible PRF value is decreased automatically, when the RANGE value is increased and vice versa, if the RANGE value is shortened, then the PRF value increases up to the preset value. 4.2.9 SPIKE/BURST Selection of the pulser mode: SPIKE low energy, single pulse; BURST high energy, single pulse or series of pulses, max. 10. 4.2.10 P.FREQ Adjustment of the pulse main frequency: 0.10 to 33.33 MHz.

6) In order to enable correct basic measurings, set the correct VELOCITY for used ultrasonic wave. 7) Set PROBE DELAY to the probe/material interface, as for conventional angle probe, then S, P, D should correspond to the bottom reflection (P is the distance from the probe index point to the weld axis, D is material thickness). 8) Set the time base range to make visible lateral echo (it runs the shortest path under surface) and bottom reflection echo for used wave (probably longitudinal). Area, where will be displayed diffraction of longitudinal wave, will defined this way. 9) If there is any discontinuity in the weld axis, then another echo appears between two echoes, Gate1 start point should be set to the lateral echo (which is constant for given distance between probes), and the end point should be set to the evaluated echo. Approximate reflector depth D=xx will be calculated based on the time difference between lateral and discontinuity echoes and the distance between probes 2S; the D value is displayed blue next to the gate, S is only for information regarding the distance from probes to the weld axis. NOTE: The half distance between probes should be set in the AUTOCALIBRATION mode (see 7.2. Automatic Calibration of Probe Delay and Sound Velocity) as S1, thus S2, which is double, is full distance between probes. DRC Srl 2012 44/102

DRC Srl 2012 57/102

5.1.4 Functions of GATE 1 with DAC Curve When any DAC function is ON, all amplitudes are measured against the basic DAC curve (DAC1), instead the GATE1 vertical position of the gate has no effect. In the Status window, the following values are displayed: a) with ANGLE function OFF: (see also 4.6.7 or 4.9.7) - (1) DAC db maximum echo peak (marked with red cross ) relative amplitude against the DAC curve [db] within the Gate 1; (1) (2) (3) - (2) AP maximum echo peak (marked with red cross ) absolute height within the GATE 1 [% FSH]; - (3) 0-P position of the maximum echo peak (marked with red cross ) within the Gate 1. b) with ANGLE function ON: (see also 4.6.7 or 4.9.7) - (1) S=XXmm non-corrected sound path position of maximum echo peak (marked with red cross ) within the GATE 1.

5.1.5 Other Functions of GATE 1 - Acoustic alarm may be switched ON, when the echo reaches or exceeds the GATE 1 level or, with DAC switched ON, when the echo reaches or exceeds the DAC level within the GATE 1 (GATE 1 level has no effect, when DAC is ON). - ON+AUX: analog output may be switched ON. There is a signal on the AOUT1 output (LEMO Analog Out), with voltage corresponding to relative echo position within GATE 1 (see also 6. Functions of Analog Output): minu = GATE1_BEGIN; maxu = GATE1_END. - When GATE1 is set to ON+AUX and GATE2 is ON, there is a thickness value on the AOUT2 output. - When GATE1 is set to ON+AUX and GATE2 is OFF, there is an echo amplitude within the GATE1 on the AOUT2 output. - ON+A/TTL: sends echo position to AOUT1 ouptut and a TTL logic signal about echo presence within GATE1 on AOUT2 output (see also 6. Functions of Analog Output). Note: If there is no echo within GATE 1, then maxu is on the output. DRC Srl 2012 59/102

The position of first echo peak within GATE 1 (which exceeds GATE 1 level) is taken as the reference. - Minimum THICKNESS shall be set in the right side of the GATES menu. This THICKNESS value (T>x.xx) is added to position value of first echo found within GATE 1 and determines a zone to search a second echo. This zone is indicated on the screen as GATE 2 with variable width, if at least first echo has been found within GATE 1. - A first echo peak is now searched within GATE 2. Its position is indicated with cyan cross. The relative position against the reference is the resulting thickness, which is displayed in the Status window with dark blue colour. - With proper GATE 1 position, width and minimum thickness setting, you can get automatic thickness gauge, operating within wide range, which doesn t require any operator s intervention. - If measured values are very unstable and their variation exceeds certain limit, then minimum measured value will be displayed, because highly probably there is some unwanted echo within the gate, which interferes with measuring. DRC Srl 2012 60/102

5.2.3 THICKNESS 1P-1P - GATE 1 shall be positioned across first echo, GATE 2 shall be positioned across second echo at discretion. - When both gates are overpassed, thickness is determined by the difference between positions of first peaks of first echoes within gates. - Measured echo shall be whole within the gate, i.e. gate shall not start inside the signal. Otherwise next whole echo (half wave) will be used. 5.2.4 THICKNESS F-F - GATE 1 shall be positioned across first echo, GATE 2 shall be positioned across second echo at discretion. - When both gates are overpassed, thickness is determined by the difference between positions of flanks of first echoes within gates. - Measured echo shall be whole within the gate, i.e. gate shall not start inside the signal. Otherwise next whole echo (half wave) will be used. 5.2.5 THICKNESS P-P - GATE 1 shall be positioned across first echo, GATE 2 shall be positioned across second echo at discretion. - When both gates are overpassed, thickness is determined by the difference between positions of peaks of first echoes within gates. - Measured echo shall be whole within the gate, i.e. gate shall not start inside the signal. Otherwise next whole echo (half wave) will be used. DRC Srl 2012 61/102

5.3 GATE 3 5.3.1 Available Modes of GATE 3 - OFF, - ON (positive logic) without any alarm, - ON + (positive logic) with acoustic alarm, - ON - (negative logic) with acoustic alarm - AUTOFREEZE any signal within GATE 3 level, which exceeds the gate level for 1 sec. or more, will cause automatic freezing of actual picture (screenshot), indicated by the red indicator *FROZEN*. The picture then may be saved see 3.6.2. This function is used with SPOT WELD mode (optional). 5.3.2 Function of GATE 3 Intended use monitoring of back wall echo etc. Fully independent GATE 3 may be switched ON in any operation mode of the instrument. It measures echo position and echo peak height (% FSH), marked with yellow cross. Values are displayed directly underneath the gate. Acoustic alarm with positive and negative trigger logic may be applied. There is a possibility of GAIN correction within GATE 3 for monitoring of back wall echo simultaneously with small defects detection. Actual GAIN correction (GATE 3 ±XX.X db) is displayed at the center of the right section of the display (instead the REJECT value) in the GATES menu with GATE 3 switched on (ON, ON + or ON -). Notes: If required gain correction within GATE 3 cannot be executed due to actual setting of the attenuator and basic GAIN, a figure of the gain correction is displayed in red colour. Info about actual gain correction is displayed with small text directly under GATE 3 ON. DRC Srl 2012 62/102

5.4 GATE 4 5.4.1 Available Modes of GATE 4 - OFF; - ON (positive logic) without any alarm; - ON + (positive logic) with acoustic alarm; - ON - (negative logic) with acoustic alarm; - ECHOSTART time base start is synchronized with interface echo within GATE 4; - ES+AUX analog relative position of echo flank (within GATE 4) on ANALOG OUT1; - API 5UE special function for evaluation of surface indications acc. to API 5UE see 7.6. API 5UE Mode Evaluation of Indications acc. to API 5UE. 5.4.2 Function of GATE 4 Intended use echo-start for immersion testing etc. Functions of GATE 4 are exactly the same as GATE 3. GATE 4 has its own velocity of sound propagation. Thus, it is possible to measure distance in water (or other liquid) independently on distance in the material under test. In addition, there is ECHOSTART function, which shifts the waveform so, that the echo within GATE 4 is kept at its left limit. Thus, variable distance from the transducer to interface (e.g. immersion testing) becomes static on the screen, that allows positioning of other measuring gates to stable positions relative to the GATE 4 (interface). The original echo position within the GATE 4 is indicated with pink cross. If echo disappears from within the GATE 4, then the waveform is displayed nonshifted in its original position. When the last option had been chosen, i.e. EchoStart+AUX, then there is a signal on the AOUT1 output (LEMO Analog Out), with voltage corresponding to relative echo position within GATE 4 minu=gate4_begin, maxu=gate4_end. Note: If there is no echo within GATE 4, then maxu is on the output. DRC Srl 2012 63/102

CURVES Sub-Menu (SETTING): Notes: Cross mark, indicating the echo peak against DAC, is red, when over the curve, or pink, when its position is known (within the GATE 1 range). In the DAC mode, echo db value and position are related to the curve, not to the horizontal gate. DAC curve may be constructed using up to 20 points, which may be set in any order they will be automatically arranged in the ascending order. 7.3.2 DAC Interpolation Modes (DAC INTERP.) See also 4.8. CURVES Sub-Menu (SETTING): - LINEAR - adjacent DAC curve points are connected by straight lines; - LOG/LINEAR - adjacent DAC curve points are connected by curve with constant slope in db/m; - LOG/LOG - adjacent DAC curve points are connected by curve with slope corresponding to db/depth ratio (when two points are related to the same reflector size in different depths). 7.3.3 DAC Modes (DAC MODE) See also 4.8. CURVES Sub-Menu (SETTING): There are two DAC modes available: - FIXED - the DAC curve will not change its position, when the GAIN value changes; - NORMAL - the DAC curve moves accordingly to the GAIN value change, i.e. trigger level is constant.

7.3.6 JIS-DAC JIS-DAC mode (Japanese standard) is similar to common DAC mode. See also 7.3.2 for DAC interpolation modes and 7.3.3 for DAC modes. The reference (basic) JIS-DAC curve may be set and then adopted from the DAC TYPE 1 (see 7.3.2), or may be set directly as DAC TYPE JIS-DAC6 by the same procedure using calibration reflectors in the reference block. The difference compared to DAC is that 5 (five) auxiliary curves will be set automatically with fixed predefined offsets: L-LINE -12 db (light blue); M-LINE -6 db (magenta); H-LINE ±0 db (pink dashed basic curve); U-LINE +6 db (red); U -LINE +12 db (orange); U -LINE +18 db (yellow). Triggering level may be set to whichever of displayed curves by appropriate setting of the TRIGGER value (L-LINE to U -LINE). In the Status Window, an indication within the GATE 1 range is assigned to one of seven zones (I to VII), in addition to relative db value: Zone I below L-LINE; Zone II between L-LINE and M-LINE; Zone III between M-LINE and H-LINE; Zone IV between H-LINE and U-LINE; Zone V between U-LINE and U -LINE; Zone VI between U -LINE and U -LINE; Zone VII above U -LINE.

7.6 API 5UE Mode Evaluation of Indications acc. to API 5UE Notes: GATE 4 has its own velocity, which can be set in range from 1 m/s up to 20000 m/s. AWS MODE shall be OFF see 4.8. CURVES Sub-Menu (SETTING). 1. Activate the API 5UE function either in the SETTING CURVES menu see 4.8, or in the GATES menu see 4.4.5. GATE 4 shall be active in API 5UI mode (pink indicator 4fx in the Status Window). 2. Depress the key (Display Freeze) for longer than 1 sec, the FREEZE MAX mode of A-scan is activated with red indicator *PEAKS* in the Status Window see 3.4. The maximum signal envelope is displayed simultaneously with live echo. 3. With active FREEZE MAX mode, move probe over a calibration notch in the reference block and get envelope shape. Bring GATE 4 over the echo and adjust VELOCITY value (pink for GATE 4) to get calibrated size of the reference notch. The value is displayed in Status Window as API fx= xx.xx [mm or inch]. In order to display value of the notch under the test, echo from the notch shall cross the GATE 4 level GATE 4 level shall be adjusted accordingly. The width of peak at half level of echo amplitude measured with GATE 4 is used for calculation, velocity multiplied by amplitude/100% FSR (Full Screen Range), so if echo peak is 100% of screen, then coef = 1. API 5UE function works in combination with all other modes, except RF mode. When AWS function is activated, value is displayed on the same position in Status Window as API value, but when FREEZE MAX is activated, API 5UE has preference. DRC Srl 2012 77/102

7.7 Curved Surface Metric The curved surface metric is very useful function for inspection with angle probe on curved surface of object to be inspected. This function may be activated from within the SETTING menu see 4.6. Some parameters of angle probe shall be set in the SETTING menu prior to use this function: ANGLE and X-VALUE. Then actual geometrical parameters of the object to be inspected shall be set as well: CURVED SURF. INSIDE (concave) or OUTSIDE (convex); DIAMETER and THICKNESS. The skip lengths are calculated automatically and displayed as white zigzag line in the upper part of the screen. In the Status Window, the parenthesis symbol ( next to the D and P symbols indicates that depth of flaw D( and surface projection distance P( are calculated from the outside (convex) surface and vice versa, the parenthesis symbol ) next to the D and P symbols indicates that depth of flaw D) and surface projection distance P) are calculated from the inside (concave) surface. The symbols /\/\ next to the sound path value S in the Status Window indicate, in which half skip is flaw located. If a relation of outside diameter D and thickness T is D <= 2*T, then material will be considered as full and the cutting reflex is assumed. In such case, the symbol (O) under the DIAMETER value is changed to O; in addition, SKIP XX.X mm is changed to SKIP (\) XX.X mm. If the combination of sizes is nonsense, then projection distance axis ~Pmm], P and D values are not displayed, with pink SKIP error message under the CURVED SURF. DRC Srl 2012 78/102

The PA MODE has changed to Chan SEL TX & RX. One more additional parameter appeared APERTURE. The APERTURE enables to change the number of active elements within PA probe and, thus, create a probe with variable width. The indication N..M TX&RX just under the PA[1..16] indicates the position range of such group of elements in the probe, which may be moved within 1 st to 16 th element using appropriate grey and yellow Control Keys. Example shows elements 3 to 5 with APERTURE 3. All chosen elements transmit and receive non-phased waves. APERTURE=1 serves to check each element separately, whether it works, have proper coupling etc. After L-scan (Linear scan) had been activated (green), all positions within the probe are cyclically activated, e.g. there are 16 positions for APERTURE=1 and A-scans are displayed from each sound beam. Then PA[1..16] Control Keys serve to move the cursor for A-scan display from the specified step (element). This mode may be used for fast scanning using big wide probe (like a paint-brush) for testing thickness, laminations etc. would be anything below the probe, the back-wall echo position will be changed; if all is OK, then all 16 rows are similar, with red backwall echo only.

10.5 Firmware Update DRC electronics constantly improves the firmware to satisfy demands of users and requirements of new standards and/or specifications for ultrasonic inspection. Updated firmware is distributed via e-mail or using other data carrier. Complete folder (directory) D1000 for upgrade, which is distributed via e-mail, is packed in one ZIP file. In order to download new firmware, it shall be saved from the computer (PC or laptop) to the USB flash memory stick extracted to the root of the USB flash memory stick, strictly retaining the original structure:..\d1000 [main files: D; diomap; fpga; fpga.bin; fpgaomap; fpgapa *) ] \data [data files] if any not necessary for firmware update \lang \help [help file(s) in.png or.jpg picture format] [interface language files language_str.txt ] \pictures not necessary for firmware update [printscreen files.png, associated data and settings files.dat,.stp,.csv,.htm] \setups not necessary for firmware update [setup files.txt] *) for D1000-PA only 1. Connect the D1000 to the power supply and switch ON. 2. DO NOT SWITCH OFF NOR DISCONNECT THE USB DEVICE DURING ANY USB OPERATION! 3. Connect the USB memory stick to the USB port of the instrument (using the special connecting cable and USB memory stick delivered with the instrument); 4. Depress the? key switch to special help mode; 5. Depress the key activate the USB SERVICE mode: - the instrument will check, if any USB device is connected the USB SERVICE mode may be interrupted during this operation; - then system looks for firmware in the D1000 folder; and if any fpga.bin and/or fpgapa.bin file had been found, a warning will be displayed: -! WARNING: D1000 firmware update files found on USB dick! - Do you want really uprate firmware?? UPDTE CANCEL 6. downloading process takes several minutes, DO NOT REMOVE the USB memory until the message indicating the successful download appears in the bottom row. DRC Srl 2012 97/102

IMPORTANT NOTES: After firmware had been updated, it is advisable to rename the D1000 folder on the USB memory stick to D1000.yyyy.mm.dd. This assures, that it will remain as a backup and will not be changed during next connection to the instrument later. Every time during the firmware update (even with new empty USB memory stick with no firmware), all saved records (pictures with settings etc.) will be saved to the USB memory stick in the /D1000/pictures folder (if there is enough space on the USB memory stick) and at the same time all records will be erased in the instrument. The USB SDERVICE function may be used also to move All picture records to the USB device at once. In this case, it is advisable to use empty USB device with NO D1000 folder it will be created automatically. Otherwise, the firmware will be always re-updated at each start of USB SERVICE. Records from the USB memory stick may be downloaded back to the instrument follow the procedure described in 10.4. Load Records From USB Memory Stick. DRC Srl 2012 98/102
