In these first six sections, you have learned
all you need to take accurate measurements.
The following sections contain calibration,
advanced operations and technical information.
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. 17).

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.
