●
Prevent the probe from receiving mechanical shock. Avoid putting excessive
strain on the probe cable or exposing it to sharp bends. Touching a broken
cable during measurements can cause injuries.
●
Set up all probe connections to the instrument before applying power.
Working with current probes
When working with current probes, you can measure high-frequency currents or
currents that contain high-frequency components.
●
Switch off the test circuit while connecting the probe.
●
Do not attach the clamp to bare unisolated conductors. To avoid injury from a
short circuit, measure at a location on an insulated wire where the insulation is
sufficient for the circuit voltage.
●
Connect the probe only to the secondary side of a breaker. With this measure,
you avoid injury, if a short circuit occurs.
●
The following effects can cause burns and fire or damage to the measurement
site:
– Eddy current loss can cause heating of the sensor head.
– Dielectric heating can cause heating of cord insulation and other materials.
●
When measuring current that includes a high-frequency component, consider
the derating characteristics of the probe. Do not measure any current that
exceeds the rated current.
Using the probes with high frequencies or strong magnetic fields may cause
the device to become abnormally hot, resulting in fire, equipment damage, or
burns.
