Operation
To use:
1. Connect the clamp cable to the current inputs on the measurement
instrument. The instrument automatically recognizes the clamp and
selects the default range of the instrument for the probe.
2. Make sure the measurement instrument is set to the correct range.
3. Connect the jaws around the conductor to be measured.
Warning
To prevent electrical shock, re, or personal injury, hold the

Maintenance
Warning
To prevent electrical shock, re, or personal injury:
• Before each use, examine the Product. Look for cracks or
missing pieces of the clamp housing or output cable insulation.
Also look for loose or weakened components. Carefully
examine the insulation around the jaws.
• Do not use the Product if it is altered or damaged.
If the Current Clamp does not work or perform properly:
1. Inspect the jaw mating surface for cleanliness. If any foreign material
is present, the jaw will not close properly and measurement errors
will result.
2. Verify that the function selection and range on the measurement
instrument are correct and adjusted to the sensitivity of the Current
Clamp.
Cleaning
Periodically wipe the case with a damp cloth and mild detergent.
Caution
To avoid damaging the Current Clamp, do not use abrasives
or solvents to clean the clamp.
Open the jaws and wipe the magnetic pole pieces with a lightly oiled
cloth. Do not allow rust or corrosion to form on the magnetic core ends.
