Troubleshooting
Problem Cause Corrective action (Reference)
The output rate differs from
the specifications.
The output is small.
The 200.0 A range is used. Check the current range.
The 200.0 A has an output rate of
200 mV/f.s. This rate differs from the
other ranges’ rates .
The equipment that receives the output
has a low input impedance.
Check the input impedance of the
equipment that receives the output.
An input impedance of 100 k
Ω
or
more is recommended.
The frequency of the object under
measurement is outside the output
accuracy (15 Hz to 2 kHz) range.
The frequency band (15 Hz to
15 kHz) shows a band where the
output attenuation is ±3 dB or less.
(p. 81)
The measured value is
incorrect.
Displayed values can frequently
fluctuate due to induction potential
even when no voltage is applied. This,
however, is not a malfunction.
–
The tip of the jaws is open. Close the jaws.
The jaws are damaged.
When a jaw is damaged or cracked,
the current cannot be measured
accurately.
Have the instrument repaired.
