While demagnetization and zero adjustment is taking place, the
DEMAG/AUTO ZERO LED is lit. When demagnetization and zero
adjustment is complete, the LED turns off.
If the DEMAG/AUTO ZERO LED does not turn off but blinks even
if you press the DEMAG/AUTO ZERO switch, this indicates that
demagnetization and zero adjustment have not been completed
normally. See “Types of Errors and Corrective Actions” for details.
Note
• When connecting the probe to a non-BNC input terminal through a
BNC-to-banana adapter or the like, pay attention to the polarity of the
input terminal.
• Resonant sound may occur when you perform demagnetization, but
this has no effect on measurements.
• After starting to supply power or after a condition in which the rating
is exceeded is removed, the DEMAG/AUTO ZERO LED blinks slowly
until demagnetization and zero adjustment are executed.
• While demagnetization is taking place (the DEMAG/AUTO ZERO LED
is on), a demagnetization waveform (waveform that attenuates over
time) is output from this instrument’s output terminal and appears on
the waveform measuring instrument. The positive and negative sides
of this waveform may be asymmetric, but this is not a malfunction.
• To abort demagnetization and zero adjustment, release the sensor
head lock. Then, execute demagnetization and zero adjustment again
according to the procedure.
To Perform Only Zero Adjustment
To perform only zero adjustment (without demagnetization), press
DEMAG/AUTO ZERO
for a short time in step 4 on the previous page. The
DEMAG/AUTO ZERO LED turns on. When zero adjustment is complete,
the LED turns off.
