Calibration with custom solu-
tion.
If the cell constant was changed after calibration (through
the “CELL” setup item), this information is not displayed.
If RANGE (or NEXT) is pressed while the last param-
eter is displayed, the meter returns to measurement mode.

Notes:
•
If the meter displays only dashes "----", the read-
ing is out of range.
•
If the stability indicator (hourglass symbol) blinks,
the reading is not stable.
•
Make sure the meter is calibrated before taking
measurements.
•
If measurements are taken successively in dif-
ferent samples, for accurate reading it is recom-
mended to rinse the probe thoroughly with deion-
ized water before immersing it into the next
sample.
•
For AD332: the TDS reading is obtained by mul-
tiplying the EC value by the TDS factor (de-
fault: 0.50). This factor can be selected by the
user (0.40 to 1.00) through the "tdS" setup item
(see “Setup” section for details).

Notes:
• To exit GLP mode at any time, press SHIFT+GLP.
• If calibration has never been performed, after display-
ing the ID code, the meter will show the "no CAL"
message blinking. Press RANGE (or NEXT) or
SHIFT+GLP to return to measurement mode.
• For AD332, only last EC calibration data are avail-
able. No calibration data can be recalled for TDS. If
SHIFT+GLP are pressed from TDS measurement
mode, the meter will display the ID code only. Press
SHIFT+GLP again to return to measurement mode.
• GLP data are not affected by zero calibrations.
