Error messages after self-test
When switched on, the Testomat
®
EVO TH CAL performs a self-test
automatically and then monitors its own state continuously. If the
LEDs on the control card flash quickly after switching on, one of the
above errors has occurred and can be identified by the LED signal.
In addition, the error message is placed on the SD card in the error
log, even when the "Store error" function is inactive.
