Configuration

6.6.1

Selecting pH or ORP Mode of Operation

The alpha pH 500 transmitter is not only a pH transmitter, but
also an ORP transmitter. When configured to measure ORP,
electrode must be changed and calibrated (see Section 5.3 for
calibration procedure). ORP values are measured and
displayed in mV only.

Transmitter.

3. Press the ENT key to accept selection.

4. Press

keys together, to return to MEAS mode.

5. If the readings on the Transmitter is fluctuating wildly, please proceed to

Section 6.6.2, for a possible solution.

6.6.2

Selecting Asymmetrical or Symmetrical Mode of Operation

In some applications, there may be some electrical interference in the sample,
where the electrode is installed. The sensitive electrode picks up the signal and the
effect is displayed on the LCD.

If the electrical interference is from an AC source, the readings on the LCD
fluctuates wildly. If the source is DC, then readings will be stable, but at a wrong
value.

In such cases, switch the Transmitter to the Symmetrical mode as below:
