9.4 P3.0: View Electrode Data
Program 3 has two “view only” options that let you check the electrode parameters
for diagnostic purposes.
• From pH measurement mode, you can view the electrode’s offset and slope
values.
• From mV measurement mode, you can view the electrode’s relative mV offset
value. (pH 110 only)
9.4.1 View pH Electrode Offset and Slope
From pH measurement mode:
1. Press the SETUP key to enter Set Up mode.
2. Press the MI/▲ or MR/▼ keys to scroll through
subgroups until you view parameter P3.0.
3. Press the HOLD/ENTER key.
4. 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 ‘---‘.
5. Press the HOLD/ENTER key to proceed to
electrode slope display.
6. The display shows electrode slope in
percentage. Slope displayed will be the current
slope of the slope zone to which a measurement
is made or calibration is done.
7. At any point, you can press the CAL/MEAS key
to return to measurement mode.
