5 Chapter I General Information A. Introduction Orion s Benchtop phuture Solid State ph System is comprised of the Orion 620 microprocessor based phuture Solid State ph Meter, and the Orion 6165 Sure-Flow phuture Solid State ph Probe. Designed to be a reliable workhorse, this system is ideal for busy, multi-user, laboratory or plant environments, anywhere conventional glass ph electrode cleaning or breakage is a problem. The Orion 620 Meter is durable, compact, easy to use, and designed for use with Orion phuture Solid State probes to provide fast, accurate, temperature compensated ph measurements in any environment. ph measurements are easy with the help of advanced features such as autocalibration, user prompting, choice of 0.1, 0.01 and ph resolution, automatic temperature compensation, and diagnostic operator assistance codes. Record data via RS232 communication using the Orion 900A Printer or computer. The Orion Sure-Flow phuture Solid State Probe features a completely non-glass sensing element making it ideal for virtually any sample matrix. Combined with the Sure-Flow reference junction for easy cleaning, and on-chip temperature measurement, temperature compensated ph analysis becomes routine even in difficult samples ranging from viscous detergents to dirty waters and tomato paste to bread dough. General Information 1

6 B. Operation of phuture Solid State System The Orion 620 phuture Solid State System utilizes solid state technology to measure ph and temperature. This system is an active electronic one, where the potential developed at the sensing surface is dependent on the solution ph. This surface potential is measured with a transistor. The change in potential is translated to a temperature compensated ph reading by the meter. Due to these special characteristics of this system care must be taken to ensure that the device is handled properly: Always turn the meter off prior to connecting or disconnecting the probe. The system is protected against electrostatic discharge (ESD). However, as with any electronic device, care should be taken to prevent large static discharges from contacting the probe. 2 General Information

7 Chapter II Instrument Description A. Display The Orion 620 has a large custom LCD display. ph results are displayed in the large main field. Temperature readings in degrees centigrade, C, are displayed in the lower field. The current mode is indicated along the top of the display. The buffer(s) used during the last calibration performed are indicated by the buffer indicators, along the bottom of the display.

9 Chapter III Instrument Set-Up A. Power Source The Orion 620 Meter is designed to operate with Orion Line Adapter for 110V operation or Orion for 220V operation. Plug the line adapter securely into the meter power receptacle then into an appropriate wall outlet. NOTE: The meter has a gasket to help prevent moisture penetration. Firmly push the power adaptor into the jack on the back of the meter. B. Stand Adjustment The Orion 620 Meter can be adjusted to provide the optimal viewing angle via a two-position flip stand. Adjust the viewing angle by gently lifting the stand with both hands and rotating to a 90 angle. Gently pull the stand and rotate beyond 90 to lock in the second position. The first position allows easy viewing from across the lab, the second position is more useful for working with the meter at the lab bench. Instrument Set-Up 5

10 C. Electrode Connections NOTE: Always turn meter off before connecting or disconnecting phuture Solid State probe. Failure to do so may damage your probe. Attach Orion phuture Solid State ph Probe or to the sensor input on the meter by sliding the connector on straight until firmly in place. The connector has a special sealing mechanism to prevent moisture from penetrating the meter. It is sealed when the connector is properly attached. Power ATC Ref. Input Rec. Gnd.

11 Chapter IV Using the Instrument A. Power Up Pressing the power key will turn on the meter. The entire display (all annunciators) will be displayed for 2 seconds. Next, the number 620 will then be displayed for 2 seconds. Then the calibration buffer(s) used for any previous calibration will be displayed in the lower display field for 2 seconds. The calibration buffer indicator(s),, along the bottom of the display, will then light up and remain displayed along the bottom of the display, until a new calibration is performed. For example: If a one-point calibration had been previously performed, the ph 7 buffer indicator will be displayed. If a two-point calibration with ph 7 and ph 4 buffer had been previously performed, the ph 7 and ph 4 indicators will be displayed. Once all power up procedures have been completed the meter automatically advances to measure mode. NOTE: If this is the first time the meter has been powered up it is recommended that the Instrument Check Out procedure be performed before using the meter for ph measurements. Using the Instrument 7

12 B. Instrument Check Out Procedure It is recommended this procedure be performed when the meter is received and any time operation problems arise. This procedure verifies the proper operation of the Orion 620 Meter. 1. With the meter power off, attach Orion phuture Solid State ph Probe or to the meter. 2.

14 Manual Buffer Option When the manual buffer option function is entered the current setting will be displayed as STD 57O or SET 5E7 on the temperature display. When the 57O option is selected, calibration may only be performed with standard buffers, ph 4.01, 7.00 and When the 5E7 option is selected, calibration may be performed with user defined buffers within the range of 0 to 14 ph. D. Millivolt Mode Scroll through Mode until MEASURE (mv) is displayed. The mode sequence is: MEASURE (ph) > CALIBRATE > MEASURE (mv) > SETUP While in the millivolt mode: The MEASURE annunciator will blink to distinguish it from the ph Mode. ready will be displayed the same way as it now is in the MEASURE (ph) Mode Direct Display of Millivolts: The mv Mode displays millivolt readings in two ways: 1. If the number is not calibrated, the display will read The user must perform at least a one point calibration before millivolts can be displayed. 2. If the meter is calibrated, the sensor reading will be converted to a millivolt reading based on a normal Nerstian slope of millivolts per decade of ph. Error codes (E-20, etc.) will be displayed in the millivolt mode for the same reasons they are displayed in the ph mode (reading is out of range, etc.). Check error display code section in the appropriate meter and/or probe instruction manual for appropriate action to be taken. 10 Using the Instrument

15 Chapter V Calibration and Measurement A one or two buffer calibration should be performed before ph is measured. It is recommended that at least two buffer calibration using buffers that bracket the expected sample range be performed at the beginning of each day to determine the slope of the electrode. This serves the dual purpose of determining if the phuture Solid State system is working properly and storing the slope value in the meter memory. The Orion 620 Meter features both autocalibration when using standard buffers, 4.01, 7.00 and 10.01, as well as manual calibration when non-standard buffers are required. A. Autocalibration Autocalibration is a feature of the Orion 620 Meter that automatically recognizes the standard buffers 7.00, 4.01 and Simply select the buffer sequence that best fits your application, choose between, a one point autocalibration with ph 7, a 2 point calibration using 7-10 or 7-4 and a 3 point calibration using 4, 7, 10.
