7.9 Electrode Zero
After entering setup mode, select “Electrode Zero” and press to perform zero-point
calibration. The user can determine if zero-point calibration is necessary from deviation of the
electrode’s measurement values. If calibration procedure is necessary, the electrode must be
placed into distilled or deionized water for zero-point calibration.
Note: When performing zero-point calibration, factory default electrode output signals will be
altered.
The transmitter will
display the 2mA current
sent from the electrode
signaling that zero-point
calibration is being done
internally.
Enter “Clean” Setup
Press to confirm it.
Select YES and press
Select NO to exit zero-point
calibration, and press
The transmitter will
display the 4mA current
sent from the electrode
signaling that zero-point
calibration is complete.
