Usage Notes
Reference
• To measure DC or low-frequency current, multiple
windings may be used to increase relative sensitivity (10
windings multiplies the measured current by a factor
of 10). However, in this case, the windings should be
made radially, with a diameter of at least 20 cm.

φ 20 cm or more
• The measurement may be affected by the position
within the sensor aperture of the conductor being
measured. The conductor should be in the center of
the sensor aperture, and the straight portion should be
as long as possible. Avoid positioning the conductor so
that it is wound locally around the sensor head.
• To facilitate accurate measurement, press the opening
lever until the JAW UNLOCKED indicator turns off
before making a measurement to ensure that the
sensor head is securely closed and locked.
• Cord placement and the act of clamping the probe
onto the conductor being measured may trigger load
fluctuations, affecting the observed waveform.
