‘READY’ annunciator when the reading is stable.
Press ▲ or ▼ key to set the upper display to the newly calculated offset
value.
3 As the upper display value (offset) changes, the pH Transmitter adjust the
lower reading automatically to suit the new offset value. Up to ± 2.00 pH
offset is allowed.
Press ENT key to confirm the value. The pH Transmitter reverts to OFS
screen.
NOTE: To exit from any intermediate steps, press ▲ and ▼ keys (Escape)
together. It will return to measurement mode.
5.3 Temperature Settings
Automatic Temperature Compensation (ATC):
The pH values other than pH 7.00 are affected by temperature. Use ATC feature of
the pH Transmitter to compensate for pH changes when the temperature of the
sample or process liquid fluctuates. Connect a separate temperature probe
(Pt100/pt1000) to the pH Transmitter if an integrated pH/Temperature probe is not
available.
Manual Temperature Compensation (MTC):
Set the pH Transmitter to MTC (disable ATC) when the temperature of sample or
process liquid is constant and a temperature probe is not available. If you disable
ATC, the pH Transmitter allows you to set your process temperature (P.ºC) and
calibration temperature (C.ºC). This allows calibration at a different temperature
other than the process temperature. Example: Setting calibration temperature of
25°C lets you calibrate using standard solutions at 25°C, even if your process
temperature is different from 25°C.
