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.
