1. After configuring the dip switches,
connect the input to a calibrated ther-
mocouple source. Connect the out-
put to the actual device load (or a
load approximately equivalent to the
actual device load value) and apply
power.
NOTE: To maximize thermal stability,
final calibration should be performed in
the operation installation, allowing
approximately 1 to 2 hours for warm up
and thermal equilibrium of the system.
2. Set the calibrator to the desired
minimum input and adjust the zero
potentiometer for the desired mini-
mum output.
3. Set the calibrator to the desired
maximum input and adjust the span
potentiometer for the desired maxi-
mum output.
4. Repeat steps 2 and 3, if necessary
for best accuracy.

Note1: All modules are designed and tested to operate in ambient
temperatures from 0 to 55°C, when mounted on a horizontal DIN rail.
When five or more modules are mounted on a vertical rail, circulating air
or model DRG-HS01 Heat Sink is recommended.
