1.8 When the reading has stabilized, the display will show CAL3.
The meter prompts you to continue with third point calibration.
1.9 Repeat the steps 1.6 and 1.7 above until the meter shows .
Calibration is completed.
To exit the calibration without saving changes, press the Meas key.
Viewing the Calibration Log
2.1 Press the MR key in the ion measurement mode and press the
key until the meter shows / (Electrode / Page 2).
2.2 Press the Enter key, the meter shows the last calibration date.
2.3 Press the key to view the calibration point and mV value.
2.4 Press the key to view the next data set.
2.5 To exit the calibration log, press the Meas key.
If the meter is not calibrated with standard solutions, the display will
show ---- only.
Ion Measurement
1. Rinse the ion selective electrode with distilled water. Place the
electrode (and temperature probe) into the sample solution and
stir gently. Note, the ion sensitive membrane and liquid junction
must be completely immersed into the solution.
2. If the Auto-Hold option in the setup menu is enabled, the meter
will automatically sense a stable reading and lock measurement,
the icon appears on the display. Press the key to resume
measuring.
If the option is disabled, the meter will continuously measure and
update the readings.
3. Wait for the measurement to stabilize and record the reading.
4. When all of the samples have been measured, rinse the electrode
with distilled water.
• During the measurement process, never wipe the ion sensitive
membrane, blot dry with a lint-free tissue to remove waterdrops
on electrode.
• If the meter is not calibrated with connected electrode, the display
will always show 0.000.
• If the meter shows ---- indicating the measurement exceeds the
range, remove the electrode from the sample immediately.
• To record the measurement at the predefined time intervals, refer
to the Interval Readings section on page 40.
