current probes
Safety
Precautions
The instrument uses an insulated BNC type connector
for connection of current probes to channels A, B, C
and N.
WARNING
Use only probes that are rated 600V CAT III or higher.
DO NOT use other probe types, including probes that
use uninsulated connectors.
Probe positioning: The arrow marking on the current
probe should be pointed in the direction of current flow
and towards the load. To reduce measurement errors,
it is always “best practice” to center the conductor in
the probe. Correct position of the probe is necessary
for correct power measurements, where in-phase
voltage and current measurements are necessary.
Contact the Dranetz for information on availability and
pricing of current probes.
The following safety precautions apply to current
probe connections.
DO NOT attempt to measure current in any circuit
in which the circuit to ground voltage exceeds the
insulation rating of the current probe (example: 600
VRMS max).
Make sure the current probes are tightly closed.
Keep mating surfaces clean and free from foreign
matter.
WARNING
DO NOT USE non-insulated current probe cores
around a non-insulated wire. Probes of this type are
designed for use around insulated wires only. Use
only completely insulated probe cores with no
exposed conductive areas of the core around non-
insulated wires.
