Temperature compensation mode
It is possible to show non-temperature compensated resistivity or non-temperature compensated
conductivity. Temperature compensation is a way of standardizing resistivity or conductivity to
measurements that would be seen if the water temperature was 25°C.
Select the preferred mode among the 3 modes of temperature compensation available:
TC1
By default TC1 mode is selected.
The resistivity or conductivity values are temperature compensated to 25°C.
The values are normalised. The system firmware eliminates small fluctuations of
temperature compensated resistivity or conductivity due to the fact that these two
parameters are not measured exactly at the same time.
TC2
The actual temperature compensated resistivity or conductivity values are
displayed. The TC2 setting should be used in applications that require the detection
of trace ionic levels or when performing the verification of the system resistivity
meter operation with an independent calibrated resistivity meter. In some operating
conditions the feed water can be warmer or cooler than the water temperature
inside the system. As a result, this can cause small fluctuations of the resistivity
and conductivity values. Resistivity values could fluctuate between 18.0 Mohms.cm
and 18.4 Mohms.cm @25°C while the actual resistivity is 18.2 Mohms.cm @25°C.
NTC
Non Temperature Compensation. The temperature compensation is off. The displayed
resistivity or conductivity is not temperature compensated. The temperature of the
water is shown at the same time as the non-temperature compensated resistivity
or conductivity value.
