•Adhere to local and national safety codes.
Individual protective equipment must be used to
prevent the shock and arc blast injury where
hazardous live conductors are exposed.
•Before each use, inspect the Probe. Look for
cracks or missing portions of the housing or
output cable insulation. Also look for loose or
weakened components.
•Use caution when working with voltages above
60 V dc, 30 V ac rms or 42 V ac peak. Such
voltages pose a shock hazard.
•Use of this equipment is designed to 600 V CAT
IV or 1000 V CAT III standards. 600 V CAT IV or
1000 V CAT III equipment is designed to protect
against the transients in the equipment in fixed
equipment installations, such as distribution
panels, feeders and short branch circuits, and
the lighting systems in large buildings.
•Do not use the Probe in wet environments or in
locations that hazardous gases exist.
Operating Instructions
1. Connect the Probe to the 1750 via the 1750 current
input jack.
2. De-energize the circuit and place the Probe around the
conductor under test.
3. Observe and take measurements as required. Positive
output indicates that the current flow is in the direction
shown by the arrow on the Probe.
Maintenance
Cleaning
Clean the Probe periodically by wiping it with a damp cloth and
detergent. Do not use abrasive cleaners or solvents. Do not
immerse the Probe in liquids.
