remember that if you change the calibration from that set at the factory you may change the
calibration at all temperatures. You may get different calibration with different baths and/or
liquids.
In order to ensure that the calibration you are setting is correct, you will need to use an independent
calibrated probe or thermometer.
Set the temperature display to the particular temperature at which you require to control. Measure the
actual temperature of the bath liquid using a calibrated probe or thermometer.
If the calibration is not correct then you can follow this procedure.
a Hold down the Up and Down buttons and then press the Set button at the same time for 5 seconds.
b The display will change from the bath temperature to “EEEE”.
c Press the ‘SET’ button and either the ‘UP’ or the ‘DOWN’ button to adjust the display to the same
temperature as the measured value.
d Press ’UP’ and ‘DOWN together to confirm the value. The display will return to the bath temperature
and the unit will control with the new calibration parameters.
