Output current range
For the pyrometer's two analogue current outputs, select the current loop
scale – (0 - 20 or 4 – 20 mA)—which matches that of the downstream
signal processing equipment (PLC, display device, controller, etc.). At
the pyrometer and at the controller, set the upper and lower limits of the
temperature range and the current loop output signal. Access this setting
using configuration layer

Simulated current signal for functional testing
After initial installation, you should perform a function test to verify that
temperature data is correctly transmitted to the controller. To do so, use
the push-buttons on the pyrometer rear panel to simulate a temperature
reading, which is applied as an output current signal scaled to the se-
lected current range. The appropriate parameter can be accessed via
configuration layer
If the pyrometer is set up correctly, the downstream controller should in-
dicate the values you have entered (only within the scaled range). If
there is a discrepancy, please check the current range scale or the cable
connection.
When you have completed the function test, exit by pressing "
return to normal operating mode.
