Two selectable temparature sources are available: reading directly from the sensor inside the probe
or manual entry.
Three options of compensating temperature are available:
Linear Temperature Compensation
:
The conductivity of a solution with a specific electrolyte
concentration changes with temperature. The relationship of the change in conductivity as a function
of temperature is described by a solution’s temperature coefficient. This coefficient varies with each
solution and is user selectable (see
SETUP
mode).
Non Linear Temperature Compensation
:
for natural water measurements.
The conductivity of natural water shows strong non-linear temperature behavior.
A polynomial relationship is used to improve the accuracy of the calculated results.
Note: Conductivity measurements of natural water can only be performed at temperatures
ranging from 0 to 36
°
C. Otherwise the “Out T range” message will be displayed blinking
.
No Temperature Compensation (No TC)
:
The temperature shown on the LCD is not taken into
account.
To select the desired option enter
SETUP
menu (see page 37).
If the temperature is out of the -20 °C - 120 °C range the instrument will do no temperature
compensation.
