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).

7. Stir briefly and wait a few minutes for the measurement to
stabilize. Measured value and unit tag is displayed for the
selected parameter.
Note:
If measurements are taken in different samples successively,
rinse the probes between measurements to avoid cross
contamination. After cleaning, rinse the probes with some of the
samples to be measured next.
Warnings
If measured value is outside the parameter limit of the probe, the
maximum or minimum value is displayed blinking.
