5.9.2 Current Alarm
■
If the current exceeds the threshold
set, the alarm symbol and the alarm
threshold blink.
■
If the buzzer is active, a low-pitched
audible signal is emitted.

5.9.3 Impedance Alarm
If there is no voltage alarm, no detection of noise, and no current alarm, an alarm
on the impedance may be triggered. If the buzzer is enabled, the corresponding
audible signal is emitted.
■
Low Threshold Configuration:
An audible signal is emitted when the
impedance is below the threshold set
(continuity type measurement).
■
High Threshold Configuration:
An audible signal is emitted at values
exceeding the threshold (detection
of a grounding impedance that is too
high).
Figure 5-6
If the impedance crosses the selected threshold, a low-pitched audible signal is
emitted.
5.9.4 No Alarm Detection
If no alarm is activated, the alarm icons are not displayed.
■
When no alarm is triggered, the
alarm threshold is displayed,
along with the direction
of triggering ( , ) of the
impedance, voltage, or current
alarm.
