Opening lever
Operating lever for opening the sensor head. Always use this lever to open the
sensor head.
Sensor head
The sensor head clamps on the conductor being measured, and carries out the
actual current measurement. It is a precision assembly including a molded com-
ponent, a ferrite core, and a Hall effect element. It may be damaged if subjected
to sudden changes in ambient temperature, or mechanical strain or shock, and
therefore great care should be exercised in handling it.
Demagnetizing switch (DEMAG)
This demagnetizes the core if it has been magnetized by switching the power on
and off, or by an excessive input. Always carry out demagnetizing before mea-
surement.
Zero adjustment dial (ZERO ADJ)
Use the zero adjustment dial to correct for the effect of a voltage offset or temper-
ature drift.
When beginning measurement, after demagnetizing always carry out a zero
adjustment.
Coarse adjustment trimmer
Use this only when adjustment is not possible within the range of the zero adjust-
ment. Use a nonconductive screwdriver (e.g. ceramic driver) for adjustment.
Output connector
Connect to the BNC input connector of the waveform measuring instrument.
The current waveform of the measured conductor is output at a constant rate
(0.1
V/A).
Power plug
Connect the plug to the R&S
RT-ZA13 probe power supply receptacle to supply
power to the sensor.
