Under certain circumstances, oscillation may occur if the probe is connected to the power
supply while the power supply is on. This does not indicate a malfunction. Oscillation can
be stopped and operation restored to normal by opening and closing the sensor head.
Depending on the measured current frequency, some sound maybe produced by resonance,
but has no effect on measurements.
The reading may be affected by the position within the clamp aperture of the conductor
being measured. The conductor should be in the center of the clamp aperture.
When carrying out a measurement, press the opening lever until the UNLOCK indication
disappears and check that the sensor head is properly closed. If the sensor head is not
properly closed, an accurate measurement is not possible.
Accurate measurement may be impossible in locations subject to strong external magnetic
fields, such as transformers and high-current conductors, or in locations subject to strong
external electric fields, such as radio transmission equipment.
At high frequencies, common mode noise may affect measurements taken on the high
voltage side of circuits. If this occurs, reduce the frequency range of the waveform
measuring instrument or clamp onto the low-voltage side of the circuit.
