This mode lets you recall previous pH calibration data,

which helps you know when to re-calibrate your meter.

This is a “view only” mode.

mode if necessary.

2. Press the SETUP key to enter Set up mode.

3. Press the ▲ or ▼ keys to scroll through

subgroups until you view parameter P1.0.

4. Press the ENTER key repeatedly to view previous

calibration data. See figure on right.

• 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

5. When you have scrolled through all calibration

data, you will automatically return to the subgroup

menu. Press CAL/MEAS key to return to

measurement mode.

NOTE

If there is no previous calibration data at a particular
