for HMM
Attention: Doesn't concern a new device or a
device 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 °C (or 32 °F
– 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.
