5. Temperature compensation

Two options are provided for temperature compensation:
1) Automatic compensation with temperature sensor connection
Ensure that the temperature sensor consistently records the temperature that the elec-
trode is exposed to. When the temperature sensor and the electrodes are not in the same
solution, we recommend that you opt for manual compensation.
2) Manual compensation
If the temperature remains sufficiently constant, it is also possible to set the temperature
manually. The device then constantly compensates the measurement value based on the
temperature influence of the temperature as set.

Temperature measurement calibration

If the temperature sensor is hooked up using dual-lead technology slight variations in tem-
perature measurements may occur. The temperature measurement can thus be calibrated.
Measure the temperature once manually while putting the device into operation and
correct for the temperature measurement accordingly.
