OPERATING PRECAUTIONS
■
When using a D clamp first connect it to the measuring instrument before clamping
around the conductor.
■
Do not use the clamp when the voltage, with respect to earth, of uninsulated busbars or
conductors exceeds 600V rms sinusoidal or 848V crest.
■
Never leave the clamp around a conductor unless it is connected to a measurement
instrument.
■
Remove the clamp from the conductor before changing range.
■
Maintain the cable or busbar central in the clamp and hold it perpendicular to the
conductor.
■
Whenever possible avoid the proximity of other conductors which might produce fields
of interference.
■
Keep the jaw faces clean. If necessary clean them with a lightly oiled soft rag, to avoid
oxydisation.
■
Avoid leaving the clamp in very damp places or exposed to running water.
