Bench Calibration pH
The following procedure steps through the bench calibration of the pH
level.
Value from last calibration. If NEW SENSOR, effi-
ciency will be 98%. This value can be changed if
desired. A change in efficiency will affect the calibra-
tion span.
The current PH value is displayed. Enter the desired
PH value.
This value is recalculated during each calibration.
This value shows the offset change over time for a
particular sensor. Value resets to 0.00 pH if installing
a new sensor.
