Chapter 5 | Calibration Of Temperature Sensor - DRAMINSKI MOISTURE METER Manual De Uso

Calibration of temperature sensor in a new probe
for HMM
Attention: Doesn't concern a new device or a de-
vice sent from repair service.
Procedure:
1. Before starting calibration process it is necessary to
prepare:
– a bucket/bowl etc. filled with water and ice. Ice
flowing in the water guarantees that the water
will have 0 degrees Celsius.
– a bucket/bowl etc. filled with warm water
– a thermometer
2. Attach the new probe to the main unit. Put the
probe into the bucket with warm water and leave it
inside for about 5 minutes until the probe will reach
temperature similar to the temperature of water.
Put the thermometer into the bucket and measure
the temperature of water.
3. Press and hold 4 buttons: „MAX", „MIN", „T/M"
and „ON/OFF". Keep holding the buttons for about
1 second. Release all buttons, letters „CAL" will be
displayed.
