P2.0: Viewing pH electrode data
Program 2 has two “view only” options that let you
check the electrode parameters for diagnostic
purposes. It lets you view:
•
P2.1 = Electrode offset
•
P2.2 = Electrode slope
From pH measurement mode
1. Press
the
MODE
key to select pH measurement
mode.
2.
Press the SETUP key to enter Set Up mode.
3. Press the
▲
or
▼
keys to scroll through
subgroups until you view parameter P2.0.
4.
Press the ENTER key to select parameter 2.1.
5. The display shows the electrode offset value. It is
the mV offset at pH 7.00. If you have not
calibrated at any buffer, the primary display shows
0.00 mV.
6.
Press the ENTER key to proceed to P2.2.
7. The display shows electrode slope in percentage.
Slope displayed is the average slope based on the
pH calibrations. Default setting is 100.0.

display different values depending
on the settings & your
environmental conditions)
8. At any point, you can press the CAL/MEAS key to
return to measurement mode.
