The clip on each lead should be placed around the conductor’s insulation; direct contact
with the live conductor is unnecessary.
Position the clip on each conductor so that the point of the triangle mark on the jaw is
centered on the conductor. Note that the clip orientation has no effect.
3.
After the three leads are connected, check the phase LEDs. Each LED should be lit,
indicating the conductor to which the associated lead is connected is live. If the LED fails
to light, this indicates the conductor is de-energized. This allows you to confirm the
presence or absence of voltage within the conductor.
Note that if the network to which you are connected is a Delta-
type hookup, the LED connected to the ground/earth phase
blinks.
4.
When all three leads are connected, the instrument checks
phase rotation.
If rotation is present and in the expected clockwise direction – in
other words, the phase sequence is black, then red, then blue --
the green ABC LED lights and the audible alarm beeps
repeatedly.
If the detected rotation is in the opposite direction, the red
BAC LED lights and the alarm emits a continuous sound.
5.
When the test is complete, disconnect the leads and turn off the
instrument.
This concludes our brief demonstration of the Model 6610. For more
