5.2 P2.0 Viewing Electrode Diagnosis
This program lets you check the electrode parameters for diagnostic purposes. Depending on the last display mode,
displayed electrode information varies. Only these readings can be viewed:
Last Display Mode Electrode Property
Offset Slope
pH in mV %
Ion - in mV
mV in mV -
Figure 10: Average slope (mV)
Figure 8: slope in %
1. Enter the SETUP mode as described above. The meter
automatically goes to program 1.0.
2. Press ¿ or À key to scroll through the programs until you view ELE
in the upper display and P2.0 in the lower display. The electrode
annunciator also appears.
3. Press ENTER key to access the program P2.0. The lower display
will read P2.1.
The information you will see in Program P2.0 will depend upon which
MODE the meter was in prior to shutting the meter off:
In the pH measurement MODE:
P2.1 shows the mV offset of the electrode. Press ENTER key to go
to P2.2 (see Figure 8).
P2.2 shows the slope in % of the electrode.
In the mV measurement MODE:
P2.1 shows the mV offset of the electrode (see Figure 9).
In the Ion measurement MODE:
P2.1 shows the average slope of the electrode (see Figure 10).
4. To exit P2.0 program press ENTER key until ELE is in the upper
display and P2.0 is in the lower display. Press ¿ or À key to
select a new program OR press CAL/MEAS key to return to the
measurement mode.
