Clamp-on Ground Resistance Tester Model 6416 25
5.8 Alarm Management
The device has three distinct alarms that can be con gured.
NOTE: The (W, V, A) alarm thresholds can be confi gured in SET-UP (see §4.4).
5.8.1 Voltage Alarm
■ If the voltage (product ZxI) exceeds
the threshold set, the alarm symbol
and the alarm threshold blink.
■ If the buzzer is active, a high-pitched
audible warning signal is emitted.

5.8.2 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.

5.8.3 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 Con guration:
An audible signal is emitted when the
impedance is below the threshold set
(continuity type measurement).
■ High Threshold Con guration:
An audible signal is emitted at values
exceeding the threshold (detection
of a grounding impedance that is too
high).

If the impedance crosses the selected threshold, a low-pitched audible signal is
emitted.
