pH Calibration with Two Buffers
1. Prepare and condition the pH electrode according to
the instructions in the electrode user guide. Select
two pH buffers that bracket the expected sample pH
and are one to four pH units apart.
2. Connect the pH electrode, ATC probe and reference
electrode (if applicable) to the channel 1 or channel 2
meter inputs and note which channel was selected.
If the stirrer probe will be used, connect the stirrer
probe to the meter input.
3. In the measurement mode, press the f2 (cal) key.
4. Dual channel display only: Press the ▲/ ▼keys
to select the channel to calibrate and press the
f2 (accept) key.

reference electrode, if applicable) with distilled water
and place into the first buffer.
6. When the electrode and standard are ready, press the
f3 (start) key to begin the calibration.
7. Wait for the pH value to stop flashing. If the pH value
is correct, press the f2 (accept) key. If the pH value
is incorrect, press the f3 (clear) key, use the numeric
keypad and decimal key to manually enter the pH of
the first buffer and press the f2 (accept) key.

summary of the calibration. Press the f2 (log/print)
key to save and end the calibration, export the
calibration data to the calibration log and export the
calibration data to a printer or computer, if a printer
or computer is connected to the meter and enabled
in the setup menu. The meter will automatically
proceed to the measurement mode.
ISE Calibration with Two Standards
1. Prepare and condition the ion selective electrode
(ISE) according to the instructions in the electrode
user guide. Prepare two calibration standards that
bracket the expected sample concentration and differ
in concentration by a factor of ten.
2. Connect the ion selective electrode and reference
electrode (if applicable) to the channel 1 or channel 2
meter inputs and note which channel was selected.
If the stirrer probe will be used, connect the stirrer
probe to the meter input.
3. In the measurement mode, press the f2 (cal) key.
4. Dual channel display only: Press the ▲/ ▼keys
to select the channel to calibrate and press the
f2 (accept) key.

f3 (start) key to begin the calibration.
7. Wait for the concentration value to stop flashing and
then press the f3 (clear) key, use the numeric keypad
and the decimal key to enter the concentration of the
first standard and press the f2 (accept) key.
8. Press the f2 (next) key to proceed to the next
calibration standard.
9. Rinse the electrode (stirrer probe and reference
electrode, if applicable) with distilled water and place
into the higher concentration standard.
10. When the electrode and standard are ready, press

summary of the calibration. Press the f2 (log/print)
key to save and end the calibration, export the
calibration data to the calibration log and export the
calibration data to a printer or computer, if a printer
or computer is connected to the meter and enabled
in the setup menu. The meter will automatically
proceed to the measurement mode.

at a set time interval (operator programmed).
• Continuous – The meter will continuously measure and
update the display. No indicator is shown on the display.
• Value Change In Measurement – The meter will display a
measurement when the measurement reaches or exceeds
a set high or low value (operator programmed).
• Timed Reading – The meter will display a measurement
after a set time delay (operator programmed) and lock
and hold the measurement after the time delay is
reached. To start another time delay cycle, press the
measure key.
5. Press the measure key to return to the
measurement mode.
pH and ISE Measurements
1. Rinse the electrode (ATC probe, stirrer probe and
reference electrode, if applicable) with distilled water,
blot dry and place into the sample.
2. Record the pH or concentration and temperature
of the sample when the meter indicates that the
measurement is stable. The read type will determine
how the measurements are displayed by the meter.
3. Remove the electrode (ATC probe, stirrer probe and
reference electrode, if applicable) from the sample,
rinse with distilled water, blot dry, place into the next
sample and repeat step 2.
4. When all of the samples have been measured, store
the electrode according to the instructions in the
electrode user guide.
