9. When “CAL” stops ashing on the
LCD, press SET for less than 1 second
to conrm the value. The pen will
return to Measurement Mode for salt
measurement. To exit Calibration Mode
without saving, press SET for more than
2 seconds. This allows you to retain the
pen’s previous calibration data for the
current range as you proceed. If “CAL”
ashes on the LCD continually, check
that the calibration solution is stable and
that the input value (Step 8) is correct.
10. Repeat Steps 1-9 for other ranges as
needed.
Note…
If the standard value is over the measuring
range or 10% less, the displayed value will
be equal to the range limit or 10% of the
range limit.
