(b) Temperature calibration
If there is a difference between the indicated
temperature of the thermostat and the actual
temperature of the liquid in a sample vial, it can be
corrected by setting of temperature calibration.
In case the indicated temperature of the thermostat is
10.0 °C and the actual temperature of the liquid in a
sample vial as measured with a calibrated
thermometer is 10.5 °C, the difference correction value
(offset value) is +0.5. So, setting is required as
follows.
