Preparation for Measurements
Reference
• The DEMAG/AUTO ZERO LED flashes slowly after
the device is turned on, after input in excess of a
rating is removed, and until demagnetization and zero-
adjustment are performed.
• During demagnetization ( while the DEMAG/AUTO
ZERO LED is lit up ), the demagnetization waveform
(a waveform that attenuates over time) will be output
from the device’s output connector and displayed on
the waveform measurement instrument. The positive
and negative components of this waveform may be
asymmetrical, but this does not represent a device
malfunction.
• If you wish to perform just zero-adjustment without
performing demagnetization, press the DEMAG/AUTO
ZERO key within 0.5 sec.
• To forcibly halt demagnetization or zero-adjustment
while in progress, unlock the sensor head. You will need
to repeat the demagnetization and zero-adjustment
process according to the instructions later.
