Temperature Compensation; Linear Temperature Compensation; Non Linear Temperature Compensation; No Temperature Compensation (No Tc) - Hanna Instruments HI98192 Instruction Manual

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 35).
If the temperature is out of the ‑20 °C ‑ 120 °C range the instrument will do no temperature
compensation.
