Clamp-On Ground Tester Model 6418
2.2.3. AUTO-HOLD FUNCTION
The AUTO-HOLD function (see §2.4), freezes the measurement
automatically when the jaws of the clamp are opened. This can be useful
when you have only one hand free to make a measurement.
2.2.4 ALARMS
To facilitate making measurements, you can program an alarm on the
impedance measurement (see §2.4) and/or the current measurement
(see §2.4). You can then be aware whether the measurement is
acceptable without looking at the display.
The alarm indicator on the display
blinks and the instrument emits a
continuous audible signal.
To eliminate the audible signal, press
and hold the ► key.
If you set alarms on both the
impedance and the current, and both
alarm thresholds are exceeded, the
alarm on the current has priority.
2.3. CURRENT MEASUREMENT
The current measurement alone is identical to the current measurement
with the impedance measurement.
Set the switch to
A
.
Press the trigger to open the jaws of the clamp and
clamp the conductor in which the current to be
measured flows.
