Manual Calibration
To set the cell‑constant value directly:
1. Rinse the probe in the calibration standard and shake off any
excess solution (first beaker).
2. Place the probe in the standard ensuring that the EC sensor
(tip) is submersed (second beaker).
3. Press SETUP and use the
keys to select C.F. (cm
‑1
).
4. Press CAL/EDIT.
5. Use the
keys to modify C.F. (cm
‑1
) until the display reads
the custom standard value.
6. Press GLP/ACCEPT. “MANUAL CALIBRATION CLEARS PREVIOUS
CALIBRATIONS” is scrolled on the third LCD line. CAL and
ACCEPT tags are displayed blinking.
7. Press GLP/ACCEPT to confirm or press ESC to exit without
changing.
Note: Using manual calibration will erase previous calibrations;
and both log files and GLP will display “MANUAL” as standard.
