4 Correct temperature discrepancy
The temperature of the instrument has been calibrated before shipment. However, due
to various conditions, there might be discrepancy between the actual temperature and
displayed temperature. On such case, you may use the calibration button to correct the
discrepancy.
1 To ensure the accuracy of the temperature, please wait for at least 30
minutes after the instrument is set at a constant temperature, and
then perform the calibration.
2 Please use certified standard class two mercury thermometer to
calibrate this instrument.
3 Calibration point: Center hole of the module. Please fill the hole with
paraffin oil and immerge the thermometer bulb in it.
The method of the temperature calibration of this instrument is two-point linear
calibration. The calibration point may be set freely, and by setting the second calibration
point the same as the first calibration point, you can adjust the calibration point to one
temperature point.
For two-point calibration, if set the two points at 40
points will be automatically adjusted per the linear relationship of the two calibration
points.
