Troubleshooting
If damage is suspected, observe the information in the following chapter before
returning for servicing.
4.1
Possible Device Errors
No waveform is displayed on the host waveform measuring instrument
1. Re-execute demagnetization and automatic zeroadjustment.
2. Make sure that the input coupling of the waveform measuring instrument is set
to DC.
If the issue has not been resolved, the device may be malfunctioning. Send the
device for repair.
A resonant sound is emitted from the sensor heads
The sensor head may emit a resonant sound depending on the amplitude and fre-
quency of the current being measured. Such a sound may also be emitted during
demagnetization. This, however, does not affect the measurement accuracy.
The resonant sound emitted from the sensor heads becomes louder
The gap between the upper and lower sensor heads may have increased. Cali-
brate the device because the gap may adversary affect the measurement accu-
racy.
Demagnetization and automatic zero-adjustment cannot be performed /
Demagnetization or automatic zero-adjustment has not been completed
normally
Under some conditions, demagnetizing and automatic zero-adjustment cannot be
performed or cannot be completed normally:
●
The upper jaw is unlocked.
●
An overload has been detected.
