8.3 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 Setup mode.
3. Press the  or  key to scroll through sub-groups 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.
