P3.0: Viewing 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.
P3.1 & P3.2 : 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 ENTER key to select parameter 3.1.
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 0.0 mV.
5. Press the ENTER key to proceed to electrode slope
display.
6. The display shows electrode slope in percentage.
Slope displayed is the average slope based on the pH
calibrations. Default setting is 100.0.
7. At any point, you can press the CAL/MEAS key to
return to measurement mode.
See figure 26.
