Sensor calibration
SEnS
(sensor calibration display)
Stabilised temperature values must
be available for sensor calibration.
In addition, sensor calibration must be
performed at a usual room temperature
of approx. 20°C.
In order to perform correct
temperature calibration, the actual
temperature displayed on the unit and
the temperature at the sensor (to be
measured with a suitable temperature
measuring instrument) must be known.
The difference between these two values
can be set within ±3.0 K limits under
the
SEnS
menu item.
Example:
20.7°C
is shown on the unit display.
The temperature measuring instrument
shows
19.9°C
as the temperature
at the sensor.
– 0.8
must therefore be set under
the SEnS menu item.

NOTE
The accuracy of temperature
recording is dependent on the length
and cross-section of the lines
(see table on page 15).
