controllers)
- AND mode (relays will only close when both inputs
exceed a pre-set alarm level)
- OR mode (relays will close when one of the inputs
exceeds a pre-set alarm level)
- differential mode (reads and controls on the
difference between both inputs)

down, interference, unauthorised manipulation or
when no key is pressed for 5 minutes
Each time the instrument is switched on, it will check briefly its internal
calibrations while showing all functions of the display and the software-
version. An error message appears when sonething is wrong.
