[. . . ] Instruction Manual pH and ORP Controller/Transmitter lpha-pH2000 Technology Made Easy . . . 68X216830 rev0 06/02 Preface This manual serves to explain the use of the lpha-pH2000 series pH/ORP controller/transmitter. The manual functions in two ways, firstly as a step by step guide to help the user operate the instrument. Secondly, it serves as a handy reference guide. This instruction manual is written to cover as many anticipated applications of the lpha-pH2000 pH/ORP controller/transmitter. [. . . ] ­ 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). Press the ENTER key to confirm process temperature. 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). Press the ENTER key to confirm the calibration temperature. 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. Note down the correct temperature value. Press the or key to adjust the lower value. The upper number indicates the offset value. You can offset the temperature by up to ±10°C/±18°F. Press the ENTER key to confirm your setting. 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. Press the ENTER key to confirm your setting. Selecting relay function: press the or key to select the desired relay function ("LO"= low or "HI"= high). Press the ENTER key to confirm your selection.
