The value displayed is the temperature of the pro-
cess (interior of sensor). Default is 25
°
C.
NOTE:
If a new temperature value is entered, it is
used only for pH calibration. This change does not
affect the calibration on the temperature sensor.
Default values 4.01 and 7.00 pH. Enter low pH value
and press
. Enter the high pH value. If

Displays low pH calibration value, and the uncali-
brated pH value as determined from the input
source.
Displays high pH calibration value, and the uncali-
brated pH value as determined from the input
source.

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.
