When should you do the calibration?
To completely calibrate the meter,
clear all
previous calibration data,
(t o erase all calibration data,
see P7.1 on page 32 (Fig. G)).
To normalize to another value, see
P4.2 on page 28 (Fig. F). Before
the calibration
standard value of the normalized temp.
must be known. (Refer to the datasheet
enclosed with
your solution.)
resetting this value,
If the conductivity of measured solutions
are < 100 S, or TDS are < 50 ppm,
calibrate the meter at least once
a week for accuracy.

If the meter is used in the mid ranges,
it is needed to do calibration at least
once a month.
If the measurement is performed at
extreme temperatures, calibrate at
least once a week.
