Calibrating the unit
• Calibration range: It is possible to calibrate the unit by plus 3°C and minus 3 °C.
• The calibration controller protrudes out of the different-coloured temperature controller.
There are 3 fixed positions in the plus and minus range. Each position corresponds to ap-
prox. 1 degree centigrade.
• Do not attempt to go outside the calibration range.
How to proceed:
• Use a screwdriver for the calibration or break the supplied tool out of the holder.
• Measured temperature is too high: Keep the temperature controller at the set value and
move the calibration controller in the direction of - (minus).
• Measured temperature is too low: Keep the temperature controller at the set value and
move the calibration controller in the direction of + (plus).
Maintenance and cleaning
If necessary, clean the unit with clear water using a soft sponge or cloth.
• Do not not use cleaning agents or chemical solutions.
