7. Wait a few minutes and use the calibration screwdriver to adjust the
OFFSET trimmer until it displays the
pH value at the previously noted
temperature. See pH Buffer Values
at Various Temperatures table.
8. Press the pH key.
9. Rinse with second buffer being used for calibration (e.g. pH 4.01
or pH 10.01). Place the tip of the electrode 4 cm (1 1/2”) into the
second buffer. Stir gently.
10. Press TEMP key to read buffer temperature. Take a note of the
displayed value.
11. Press pH key to take a pH reading.
12. Wait a couple of minutes and
adjust the SLOPE trimmer until
it displays the pH value at the
previously noted temperature.
See pH Buffer Values at Various
Temperatures table.
13. Press CAL key. The pH calibration is now complete.
Measurement
1. Turn the meter on.
2. After initialization, battery status is displayed.
Replace the battery if BATT tag is displayed
blinking.
3. Connect the probe (pH or ORP) to the meter.
4. For accurate pH measurements, calibrate the
meter for pH before use.
5. Place the tip of the electrodes 4 cm (1 1/2”) into the sample.
6. Press the designated key to select corresponding measurement
mode (i.e. pH for pH measurements, mV for mV or ORP
measurements, and TEMP for temperature measurements).
