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 ... 10 V
1. Select the temperature range on the printed circuit board
using the DIP switch, see table on the module or page 19.
The DIP switches 1, 2 and 3 set the minimum input
temperature ϑ
min
.
The span (difference between minimum and maximum input
temperature) is set using the DIP switches 4, 5 and 6.
2. Professionally install module.
