Operator Information
To Use the Probe
.
WARNING. To reduce risk of electric shock, use only insulated conductors with
these probes on circuits with voltages above 30 Vrms, 42 Vpk, or 60 VDC. These
probes are not rated for bare wire voltages above 30 Vrms, 42 Vpk, or 60 VDC.
CAUTION. Toreduceriskoffire, do not connect or disconnect the current probe to
or from a live, uninsulated conductor. The core is not insulated. Always remove
power before you connect or disconnect the probe to or from bare conductors.
NOTE. An insulated conductor is any conductor that is surrounded by an
insulating material that is capable of isolating the voltage present on the
conductor. Lacquer c oatings like those typically found on transformer windings
do not pr
ovide sufficient, reliable insulation for use with current probes. The
lacquer coating can be easily nicked or damaged, which compromises the
insulating capabilities of the lacquer coating.
CAUTION. To prevent damage to the probe, do not drop the probe, subject it
to physical shock or rapid temperature changes, and do not insert insulated
conductors larger than 2.6 mm into the probe jaw or damage may result. If the
slider will not close around the conductors, do not force the slide closed, either
reduce the number of conductors, or use a smaller conductor if possible without
exce
eded the amperage rating of the wire.
1. Pull the slide switch toward you and hold the switch in position.
2. Place the conductor-under-test inside the exposed transformer core. The
arrow on the transformer end of the probe indicates conventional current
flo
w. If you place the probe on the conductor so that the arrow on the probe
matches conventional current flow through the conductor, orientation of the
displayed waveform will be correct.
3. Release the switch, allowing the probe to close.
4. Lock the slide switch. To lock the switch, push it firmly toward the
transformer (the switch will move only about 1/8th inch). Locking the
switch assures maximum contact between the two halves of the transformer
secondary. The conductor now becomes the primary of the transformer.
(When measuring current, always check that the probe slide switch is moved
completely forward into the locked position.)
