sensor is closed but not locked;
 When the slide switch is at the LOCK position, the current
sensor is locked and at this point, the UNLOCK indication
is covered (cannot be seen).
For RP1005C, there are LOCK and UNLOCK indications on the
slide switch. The current sensor is locked when the LOCK
indication is displayed on the slide switch (the UNLOCK
indication disappears).
2． Current Sensor
It is used to clamp the conductor to be measured and carries
out the actual current measurement. It is a precision
assembly including a molded component, 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 taken in
handling it.
3． Demagnetizing Switch
It is used to demagnetizing the core if it has been magnetized
by switching the power on and off, or by an excessive input.
Always carry out demagnetizing before measurement. The
demagnetizing process takes about one second. During
demagnetizing, the current probe outputs a demagnetizing
waveform.
4． Zero Adjustment Dial
Use the zero adjustment dial to correct for the effect of a DC
voltage offset or temperature drift on the device. When
beginning measurement, after demagnetizing always carry
