VII. CALIBRATION
A. Calibration Intervals
Generally, calibration is recommended about once per month with
Conductivity or TDS solutions. Calibration with pH solutions should
be checked twice a month. Calibration of ORP is not necessary (ref.
CALIBRATION INTERVALS, pg. 21).

1. Calibration Steps
a. Starting Calibration
Calibration is begun by pressing
while measuring Conductivity,
MIN/SALT, TDS or pH. Measuring continues, but the CAL icon is on,
indicating calibration is now changeable.
The reading is changed with the
and
to match the
known value. The calibration for each of the 3 solution types may be
performed in either conductivity or TDS mode.
Depending on what is being calibrated, there may be 1, 2 or 3 steps to
the calibration procedures.
