Measuring Currents
How to measure a current
IMPORTANT

Do not place the sensor close to a heat source.


Do not roughly operate the opening lever to lock the
upper jaw.


Do not subject the jaws and opening lever to force.


Do not subject the sensor aperture to force while the
sensor is clamped around the conductor.

Changes in ambient temperature and an impact
on the sensor head can cause fluctuations in the
offset voltage, resulting in an adverse effect on the
measurement accuracy.

Be sure to execute demagnetization and automatic
zero-adjustment before taking measurements.

Failure to do so can adversely affect the measurement
accuracy.
See “Executing demagnetization and automatic zero-
adjustment” (p. 33).
