The manual functions in two ways, firstly as a step by step guide to help the user operate the instrument. This instruction manual is written to cover as many anticipated applications of the lpha-pH2000 pH/ORP controller/transmitter. If you have doubts in the use of the instrument, please do not hesitate to contact the nearest Eutech Instruments' Authorised Distributor. [. . . ] Record the transmitter's pH reading at the time you take the sample. Measure the pH value of your sample using a calibrated pH tester, -held meter, or bench meter. Select the "OFS" sub-function, then press the ENTER key. SETUP HOLD SETUP HOLD PH PH 4. The display shows the current measured pH value (lower value) and the current offset value (upper value). As the and keys are being pressed to adjust the pH value, the offset value also changes. Continue with additional Setup procedures, or return to the Measurement mode by pressing the and keys (escape) simultaneously. Note: The offset sub-function is blanked out during ORP operation. 24 6. 3 Setting temperature (Set oC) sub-function SETUP HOLD SETUP SETUP HOLD HOLD SETUP HOLD SETUP HOLD O C SETUP HOLD SETUP HOLD SETUP CAL O HOLD O O C C atc 1. Select the "SET °C°F" sub-function, then press the ENTER key. Selecting temperature unit: press the or key to select the desired temperature unit "°C" or "°F". Enable/disable ATC mode: press the or key to enable (ATC ON) or disable (ATC OFF) automatic temperature calibration. ­ ATC disabled (ATC OFF): For manual temperature compensation you can set the process and calibration temperatures. This allows calibration at a temperature other than the process temperature. Example: setting a calibration temperature of 25°C lets you calibrate using standard buffer solutions at 25°C, even if your process temperature is different from 25°C. 4. Setting the process temperature: press the or key to adjust the process temperature (upper value, setting range: ­9. 9 to 125°C / 15 to 257 °F). Setting calibration temperature: press the or key to adjust the calibration temperature (upper value, setting range: ­9. 9 to 125°C / 15 to 257 °F). Setting temperature offset: The display shows the current temperature offset (upper value) and the temperature currently measured (lower value). Compare the current temperature displayed on the transmitter to a thermometer known to be accurate. You can offset the temperature by up to ±10°C/±18°F. Continue with additional Setup procedures, or return to the Measurement mode by pressing the s and t keys (escape) simultaneously. 25 6. 4 Control Relay A/Control Relay B (SP1/SP2) sub-function The SP1 sub-function determines the operating parameters for Relay A; while SP2 defines the operating parameters for Relay B. Since these groups have the same set-up parameters, they are described together. SETUP HOLD SETUP HOLD PH SETUP HOLD SETUP HOLD SETUP HOLD hi SETUP HOLD SETUP HOLD 1. Select the "SP1" (Relay A) or "SP2" (Relay B) sub-function, then press the ENTER key. Setting set point value: press or key to enter the value for set point 1 (set point 2) at which your controller will activate.
