3. Align the sensor so that the current direction indication matches the direction
of current flow through the conductor that you measure. The conductor should
be in the center of the clamp aperture because the measurement may be
affected by the position within the clamp aperture of the conductor being mea-
sured.
4. Press the opening lever until the JAW UNLOCKED indication disappears.
Check, if the sensors head is properly closed. The JAW UNLOCKED LED
turns off.
If the sensor head is not properly closed, accurate measurement is not possi-
ble.
Measuring low currents
●
To measure DC or low-frequency current, multiple windings may be
used to increase relative sensitivity (10 windings multiplies the mea-
sured current by a factor of 10). However, in this case, the windings
should be made radially, with a diameter of at least 20 cm.
●
Cord placement and the act of clamping the probe onto the conductor
being measured may trigger load fluctuations, affecting the observed
waveform.
