Description
Visible
Buzzer enabled; an alarm or a button press causes an audible
signal to be emitted.
Not Visible No audible signal is emitted.
This programming is backed-up and retrieved at each reset.
During a measurement, a long press on the ► button toggles between activation
and deactivation of the buzzer.
NOTE: Since the measurement frequency is audible, the operator hears
a beeping signal. This is neither an operating fault nor an alarm, and it
cannot be eliminated. This audible signal is amplified by the presence of
current in the loop.
