4 Calibration
Warning!! The power supply must be disconnected, before
changing the signal conditioner settings using the
DIP switches.
Failure to observe will lead to considerable damage!
4.1 Equipment
–
Power supply 24 Vdc, 50 mA
– Simulator for PT 100 or precision resistance decade
– Current meter/voltmeter that can be so calibrated, as to allow
an accuracy of > 0.1 % from the upper range value
4.2 Calibration with a signal output from 0 ... 20 mA
1.
Select the temperature range on the printed circuit board
using the DIP switch, see table on the module or pages 22
and 23.
The DIP switches 1, 2 and 3 set the minimum input tempera-
ture
ϑ
min.
The span (difference between minimum and maximum input
