10.1 Current measurement "A"
Notes:
– For best results, conductors should be centered in the clamp.
– The current sensing clamp is magnetized and a low reading may appear
even when no conductor has been covered.
– Only one conductor should be covered by the current sensing clamp.
Tips:

For low currents, you can increase the field
strength to a measurable level:
1. Wind the conductor around one side of the
current clamp as shown.
2. Take note of the measured current.
3. Divide the measured current by the number of
winds (coils).

The real current has been derived.
