Measuring Currents

To measure a low current

When measuring low DC or low-frequency low AC, you can
increase the current-detection sensitivity of the device in the
following way.
How to measure a low current
1
Coil a single conductor to be measured into several
loops with a diameter of 200 mm or more.
2
Clamp the sensor around the loops in a bundle.
This will make the conductor pass through the sensor
aperture one time more than the loop count consecutively
in one direction.
3
Arrange the loops radially as shown on the following
page.
4
Measure the current.
