Sper Scientific 850038 Pure Water Meter - Manual (Page 10)

This meter has a built-in algorithm
to linearize the measurement of
Sodium Chloride concentration.
F
or SALT calibration, you only need
to perform one-point calibration.
The previous calibration data will be
replaced after re-calibrating. For
example, if you previously calibrated the
conductivity meter at 1413 uS in the 0
to 1999 uS range, when you re-calibrate
it at 1500 uS again (also in the 0 to
1999uS range), the previous 1413uS
will be replaced in this range (0~1999uS).
However, the meter will retain the
calibration data for other ranges which
are not yet re-calibrated.
If you use solution to calibrate one range
and then manually input the cell constant
(
P5.2), the cell constant of range 1
to 5 will be changed simultaneously.

NOTE:
The temperature coefficient of the meter
o defaults to 2.1% per C (Fig. E) and
provides good results for most
applications. See Program P4.1
on page 27 to reset the coefficient.

NOTE:
The default normalization temperature
value
is 25°C.

Alternatively, refer to Appendix D to
calculate the temperature coefficient
and determine the appropriate
temperature coefficient for solution.
