The default value of the reference
temperature is set at 25°C. To normalize to
a different value, see page 33. Determine
the calibration standard value for your
reference temperature before resetting
the reference temperature. Contact the
solution distributor for the calibration
standard value of the solution.
Selecting the Calibration Schedule
Calibration is necessary and should be
performed regularly. Soak the probe
for 15 minutes before calibration or
measurement to minimize drift. If the pen
is used in the mid ranges, calibrate the
unit monthly.
If the measurement is performed at
extreme temperatures or within the
concentration listed below, calibrate
the unit weekly.
