7.3 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.
8. At any point, you can press the CAL/MEAS key to
return to measurement mode.
See Figure 27.
(The values shown above are for illustration purpose. Your meter may display different values depending on
the settings & your environmental conditions)
