From measurement mode:
1. Press the MODE key to select pH
measurement mode.
2. Press the SETUP key to enter SETUP
mode.
See figure
3. Press the ▲ and ▼ keys to scroll
through subgroups until you view
parameter P1.0.
4. Press the ENTER key repeatedly to view
previous calibration data.
P1.1 = pH 1.68
P1.2 = pH 4.01
P1.3 = pH 7.00
P1.4 = pH 10.01
P1.5 = pH 12.45
See figure
5. When you have scrolled through all
calibration data, you will automatically
return to the subgroup menu. Press the
CAL/MEAS key to return to measure-
ment mode.
NOTES:
If there is no previous calibration data at
a particular point, the primary display will
show “----”.

P2.1: Electrode offset
From 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 ▲ and ▼ keys to scroll
through subgroups until you view
parameter P2.0.
See figure
4. Press the ENTER key to select
parameter P2.1.
5. The display shows the electrode offset
value.
• the display shows the mV offset at
pH 7.00. If you have not calibrated at
any buffer, the primary display shows
0.00 mV.
See figure
6. Press the ENTER key to to proceed to
step 4 of P2.2. Or, press the CAL/MEAS
key to return to measurement mode.
pH mode—P2.0: Viewing electrode data
Program P2.0 has two “view only”options that lets you check the electrode parame-
ters for diagnostic purposes.
