-
Do not use the current clamp if it is damaged. Inspect the case before using the
current clamp. Look for cracks or missing plastic. Pay particular attention to the
insulation surrounding the connectors.
-
Inspect the clamp jaw before each use. No cracks, missing, loosen or weaken parts
shall be observed. Ensure there is insulation surrounding the jaw.
-
Inspect the cable without exposing the metal to ensure insulation.
-
Do not operate the current clamp around explosive gas, vapor, or dust.
-
Do not exceed the rated voltage/current as marked on the current clamp. Use with
extreme caution when working around bare conductors. Accidental contact with the
exposed conductors could result in electric shock.
-
Always keep your hand behind the finger guard of the clamp jaw.
-
When servicing the current clamp, use only specified replacement parts.
-
Use with caution when working above 30 V ac rms, 42 V peak, or 60 V dc.
These voltages pose a shock hazard.
-
Do not operate the current clamp if the cover is removed or loosened.
-
Use individual protective equipment if working in installations with accessible
hazardous live parts.
-
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired
-
Do not operate the current clamp around flammable gases or fumes, vapor, or wet
environments.
-
Do not connect to the BNC output or the banana plug to any power sources.
-
Use proper terminals, function, and range for your measurements.
