: Deleting of recorded alarms

If the function recording of alarms has been programmed :

The relay state is recorded after a setpoint has been passed. 
If the setpoint is passed back the other way, the relay state does not

change and the corresponding led starts to blink. 

To come back to the normal state (led not blinking and relay in the cor-

rect state) use menu CLEAr).

Reminder :

If no key is pressed during 20 s., the instrument 

will automatically revert to measure display.

Note

: An exit from mode programming with configuration saving will

reset the alarm recordings to zero.
