5 1. Scope of use The handheld device displays forces or loads sensed by strain gauge load cells. It must not be used as the only device for safety relevant measurements. 2. Operation The battery operated device supplies a stabilized excitation voltage for a strain gauge full bridge. A load change exposed to the sensor results to a change of his output signal. The device digitizes the signal and compares it to the adc-data stored in the ranges memory. Through this, loads can be displayed and the data transfered via the USB-interface to a PC. The user can store up to 16 ranges. In each of these set of data, the features of a certain sensor and display options can be stored. The setup of ranges and also a load calibration can be carried out also with the PC-software ASTAS delivered together with the device. When using sensors with TEDS or TEDS-M (masterforce sensor) the instrument will recognize the sensor automatically and it is not necessary to select a range. TEDS-M sensors include up to 6 calibration points, TEDS sensors have 0 and nominal load points stored. force transducer plug XKC or XKC 071 (TEDS) or XKC 072 (TEDS-M) Subject to technical change 03/2014 Page 1 of 35

6 3. Power supply The display can be powered either by: 3 batteries AA (HR6 Mignon) or 3 rechargeable batteries of the same size (1,2V) or USB power supply (battery display indicates full battery) or USB cable to a powered on PC (battery display indicates USB) If powering via the USB, the mounted batteries are disconnected automatically. The backlight is switched on permanently. If powered by batteries the device is switched off after 2 hours of operation (default setting). The device will be delivered with batteries mounted. To exchange the batteries open the battery compartment with a Philips screw driver. Remove the batteries if they might not be used for a very long time e.g. than powering by USB only. Battery charger, rechargeable batteries and USB power supply can be purchased from your dealer or from the manufacturer. Page 2 of 35 Subject to technical change 03/2014

8 5. Keypad functions key description function Max/min/current value To switch between the display of max/min/current value Zero To switch between net and gross value To set display (max/min/current value) to zero Unit Scroll between units (if available) Backlight On/Off (***) + Ranges Scroll to next range (if available) + Gross / net Toggle between not zeroed and zeroed display Hints for the operator ***: press for 1 second. Max/Min/Current value: When using tension transducers, tension can be defined as positive direction of force. To do this set the sensitivity value negative e.g.. -2mV/V. Zero: The zero value will be deleted when leaving a range. To store pre-loads permanently use the function ZeroLoad cal. The function is disabled when the unit mv/v is active. Auto-Tare: When the device is switched on, the display is set to zero. Pressing the zero key will switch between net and gross value in the display. The Auto-Tare-Function can be turned off by using the PC-Software ASTAS. This feature is included in all devices from Firmware-Version (see chapter ). Unit: Scroll between units that have been enabled in Ranges. If there is only one unit enabled the key has no function. In case the value to be displayed exceeds the possible range, the device switches to the next possible unit. Example: g + 15g = kg If the value to be displayed is falling, there will be no switching back into the initial unit. Backlight: The duration can be adjusted in Device setup.

9 6. Setting up Ranges General A range (channel) is stored as a set of parameter per sensor. It can be identified by a name displayed on top of the display. There is no connection between two ranges. If more then one range is defined the user needs to choose the range related to the used sensor. Up to 16 ranges can be stored in the device memory. When using TEDS-sensors or masterforce Sensors (with TEDS-M) all paramters are stored in the sensor, see also chapter 8. Therefore it is no necessary to select a range or channel in the instrument. Keypad functions for setting up key description function + Setup(***) Set up, edit and calibrate a range up One line up or raise value by one ENTER Activate menu or function save value and exit right Move cursor to the right by one digit (loop) down One line down or lower value by one Escape Exit menu or function without saving ***: press long.

Move the Cursor to Create a new range and press Enter or choose an existing range. Use the keys to move to the parameter you want to edit and press ENTER to get to the editing mode. There is always one current range. In the list of ranges it is marked with two #. The range used for the latest measuring is the current range. Parameters Base unit: (mandatory input) This unit is used for calibration. When choosing another unit in measuring mode the value displayed will be computed from the base unit value. The display of the base unit may be deactivated. Range of values: N Newton kn kilonewton (1 kn = 1000N) g gram (1 g = 0,009807N) kg kilogram (1 kg = 9,807N) t ton (1 t = 9807N) lbf pound (brit.) (1 lbf = N) oz ounce (1 oz = N) mv/v signal of a strain gage M300 MN/m² for plate load tester 300mm plate (1 M300 = 70685N) M600 MN/m² for plate load tester 600mm plate (1 M600 = N) to long ton (brit.) (1 long ton = 9964N=1016kg) Unit user defined unit Hint: The unit mv/v is calibrated at the manufacturer s site. Re-calibration by the use is disabled. When using mv/v as the base unit other units cannot be activated. Rated Load Select digits Sensitivity Overload (+) Overload (-) (mandatory input) Nominal load of the sensor in the base unit. Only integer values can be put in (mandatory input) resolution of display or decimal places range of values steps (mandatory input) output at rated load. This value will be overwritten by a more correct value acquired during calibration by load. If a calibration exists this value cannot be edited. Range of values: mv/v, default 2mV/V Overload warning in positive force direction in percent of the rated load refers to the gross value The warning Overload will be displayed if the measured force exceeds the defined overload limit in positive force direction Range of values %, default 120% Overload warning in negative force direction in percent of the rated load refers to the gross value The warning Underload will be displayed if the measured force exceeds the defined Overload (-) limit in negative force direction Range of values %, default -120% Page 6 of 35 Subject to technical change 03/2014

11 Averaging Units Name User unit User text output values per second The ADC takes 3200 samples/second. A moving average filter reduces the number of values and improves the accuracy. Use a low value for static measurements and a high value for dynamic measurements. A high value improves the quality of the Min/max value display but also allows more noise and distortions and therefore might lead to a unsteady display. Changing Average has no effect to Sensitivity. range of values: 6,25; 12,5; 25; 50; 100; 200; 400; 800; 1600 / s default: 50 / s List of enabled units defines the units that can be chosen by the user. No= unit is not accessible by the user Yes= unit is accessible by the user Values: see base unit default = only base unit = Yes name/description of the measuring range this text is displayed in the head of the display to allow easy assignment of the sensor to a measuring range Values: text, 22 characters default ##: (sequential number of range) Characterization of a user defined unit displayed symbol or text of the unit Values: text, 4 characters Default: Unit User factor conversion factor of the user unit 1 * base unit = user factor * user unit Values: in steps of 0, default: 1.0 Delete Range Change password: deletes the measuring range (possible only if no calibration exists on this range and the range to be deleted is not the only range) to define a 4 character password to protect the set up data of this range Change the password with the keys.press ENTER to save the new password. Default 0000 (After calibration at the manufacturer site, a password will be applied) Conversion of units: Units will be converted according to the SI-system. Please note that when converting force into weight the gravitational acceleration of 9,8107 m/s² (valid for Germany 3) is used. The gravitational acceleration varies according to the position on the globe. To ensure weight display accuracy of better than 0.1%, a load calibration should be carried out at the production site.

12 Device Setup T switch off Duration: Brightness: Serial-No: Firmware: (Auto off) auto power off of the device after (1 999) minutes (0 min means the device never switches off automatically) Default: 120 min If the device is powered via the USB the function is changed to standby to keep the current values Automatic switch off of the display backlight ( ) seconds (0 sec means the backlight is never switched off default: 60s Brightness of the display backlight % (10% steps) default: 80% Serial number of the device (entered by the manufacturer), read only Version of the firmware, read only 7. Calibration by load (Calibration) (only with force transducers without TEDS/ TEDS-M) The calibration is carried out by means of a known load for the current range. The calibration with a strain gage simulator is possible too. The calibration always uses the base unit. The first calibration point is zero load, the second point. A former calibration as well as the value Sensitivity will be overwritten by the new calibration. The calibration can be cancelled until the last step to keep the old data. Calibration means assigning two display values to two sensor signals. All other points will we extrapolated. A calibration of up to five points is possible with the pc-software ASTAS. Setup Mode: Press the two buttons simultaneously for longer than 1 second ( ) und ( ). Page 8 of 35 Subject to technical change 03/2014

15 Delete calibration To delete a Range the calibration must be deleted beforehand. After deletion of a calibration, zero and Sensitivity stay unaffected. The unit still displays correctly. Potential calibration point in between zero and related load (linearization points) will be removed. Display Key Function Hint >Calibration< Enter menu >Load calib: No< Delete calib: No (ENTER) ( ) >Delete calib: No< Start calib: No >Delete calib: No< ( ) (ENTER) ( ) >Delete calib: Yes< >Delete calib: is deleted< Start calib: No ZeroLoad cal ( ) (ENTER) (ESC) Delete calibration Back to menu Ranges Corrects a zero deviation of the sensor itself of/or a dead load. Please note: the overload indication is moved by the same offset. There is a risk of overload warning failure. The zero load calibration shifts the zero position of the load curve which slope is defined by Sensitivity. It should be applied after load calibration. The function is not allowed if the load calibration contains more than two points (linearization). Subject to technical change 03/2014 Page 11 of 35

16 8. ensor identification TEDS This function enable a plug and play sensor identification by the AE 703. The assignment of ranges to the respective sensors by the users are omitted and mistakes are avoided. All data regarding a particular sensor and of range are stored in the sensor and not in the display unit. All instruments after S/N (after Dezember 2009, firmware V1.3.05) can be used together with A.S.T.-TEDS-/ TEDS-M sensors. The instrumentwill automatically select the correct range. After exchanging the sensor the display unit will restart automatically and displays the following TEDS-/ TEDS-M message: TEDS rated load in N serial number or TEDS-M rated load in N serial number r TEDS/ TEDS-M sensors: TEDS/ TEDS-M sensors by A.S.T. can be recognized also on the imprint on the plug AST / TEDS/ TEDS-M. The TEDS/ TEDS-M plug is an option to a sensor with order code XKC 071 (TEDS) or XKC 072 (TEDS-M). In case a customer prefers to mount the TEDS/TEDS-M plug by himself the order code is XKC 077. The TEDS connecteor can also be used with non-a.s.t. sensors and is only compatible to specified instruments like the AE 703. How is TEDS/TEDS-M data displayed in the AE 703 For the user TEDS/ TEDS-M data appears like an ordinary range of the AE 703. Some adjustments can be carried out by the Software ASTAS only. Please note the following peculiarities: As long as a TEDS/ TEDS-M sensor is connected to the AE 703 all other ranges of the AE 703 are not accessible. A TEDS/ TEDS-M sensor can only store a two points calibration, a TEDS-M sensor can store a 6-point calibration TEDS parameters and range data can be overwritten with the manufacturers default values with the command "TEDSrestore". By this all user generated data gets lost. Data in the origin TEDS data range can only be written by the Software ASTAS in conjunction with the AE 703. This refers to Rated load, Base Unit and Sensitivity. That means that a sensor calibration is possible only with ASTAS running on a PC. All other data can be edited by means of the AE 703. Attention: Never connect a TEDS-/ TEDS-M sensor plug into a six wire (sense wires) instrument like A 810. The TEDS/ TEDS-M chip will be destroyed by the voltage of the sense pins!

18 Application notes Sensor that have different sensitivities in tension and pressure: Solution1: Create and calibrate a second range for the same sensor Solution2: Calibrate more than 2 calibration points with the pc-software ASTAS Plate load test for soil according to DIN The device supports load plates with diameters 300mm (unit M300) and 600mm. Setup a ordinary range for the sensor used (e.g. KAM/100kN) and activate the units M300 and M600 if needed. When the user chooses one the special units the force value in kn is converted to the axial stress unit MN/m² according to the DIN The display resolution can be adjusted by parameter Select digits. Calibration of the measuring chain can be carried out in kn, but also in M300 if set as base unit. If calibration has been done in KN this unit might be deactivated afterwards to prevent it from being displayed after starting up the AE 703 in the field. example: KAM/100kN Base Unit: kn Rated load 100 Selected digits: 100,0 Sensitivity 1mV/V Units: M300=YES, M600=Yes Resolution of display kn 100,0 M300 0,001 (MN/m²) M600 0,0001(MN/m²) Linearization of nonlinear sensors Use the pc-software ASTAS to calibrate 5 points plus zero Quick and comfortable edition of ranges ASTAS allows comfortable calibration and edition of a range.

The zero calibration can also be used separately for re-adjusting the zero point. Note: If there are more than 2 calibration points, the previous calibration or single additional points need to be erased before a zero calibration can be repeated. Set measured values This is for calibrating the final point as well as the further additional points. The bracket shows the maximum final value / nominal characteristic value for information. But it is possible to set a higher value for calibration. Then the following message appears: Subject to technical change 03/2014 Page 29 of 35

34 Erase all add. grid points Erase grid point Delete calibration Erases all additional grid points. Only the first and the last calibrated points (zero and final value) are maintained. Any grid point can be erased. This operation is necessary if it is intended to re-run a load calibration. Deletes the characteristic curve and sets it to the sensitivity value of the set characteristic curve. Note: The calibration is temporary in the device and can be annulated with the "Cancel" button. Permanent storage of the calibration values in the device is possible with the button "Save and Quit" only! A load calibration is not possible while a range setting or mv/v unit setting is made. Only 2 points (zero and final value) can be calibrated for a load cell with TEDS. This is indicated by the message "Load cell with TEDS" The "Range calibration" register of the Setup form opens in the background for the calibration check. Closing the calibration form will automatically close all open forms in the background. Also, in case of a TEDS cell, the TEDS form with the "TEDS Bridge" register will open in the background.
