Comparison of the measured temperature
value against a reference thermometer.
Notes:
– Due to the thermal capacity of the sensor,
it is necessary to place it in a container
with at least 2 liters of water.
– Leave the sensor and reference
thermometer in the vessel for at least 15
minutes (in the case of temperature
differences of more than 10 °C for at least
one hour) with occasional stirring so that
the temperatures equalize.
Carry out the balancing:
– Press
<ENTER>
.
– Set the measured temperature value
(upper display line) to the value of the
reference thermometer with
<UP><DOWN>
. The lower display line
shows the correction value.
