Flex current clamps A 1501, A 1502 and A 1503

It is very important that the conductor is in the centre and perpendicular to the
current censor as much as possible, in order to minimise position
measurement error.
Minimise influence of adjacent current-carrying conductors, and measure at
the point where they are far away from each other.
Make sure that the arrow marked on the clamp coupling points toward the
correct orientation for correct phase.
Keep the clamp coupling more than 2.5 cm (1 in) away from conductor.
2. Connect Flexible Current Clamps to the desired input on the measuring instrument

3. Select Phase and Neutral clamps to
Smart Clamp
in Connection setup menu on
your instrument.
4. Select appropriate Current clamp range.
5.
Observe the current value and waveform on the instrument’s display. If desired,
select the lower range on the measurement instrument.
