This requires wiring the equipment and checking relay and output functions as well as pH input (see section 2.2). This is also a good time to initially calibrate the pH electrode to the meter (see section 3). Figure 2-1.

The 100 ohm Pt RTD temperature probe can be separate from the pH electrode, built into the body of the pH electrode or (in selected models) built into the mounting assembly of the pH electrode. If an ATC input is not provided to the meter, the temperature reading will default to 25°C. If the process temperature is constant, but not 25”C, a precision resistor can be used to simulate the appropriate temperature value to the unit. For example, if the O”C, a resistor with a value of 100 ohms can control process runs at be wired to Terminals 1 and 2. The temperature display will show approximately 0°C.

It is also necessary to recalibrate the periodically. The frequency of recalibration is system dep The pH calibration procedure is as follows: 1.

Remove the electrode protector from the end o rinse the electrode with distilled woter, and buffer 7.00 solution. Press the CAL key. At this time the “CAL” annunciator light w light goes off, the first point is calibrated.
