• If servicing is necessary, or if the instrument is not operating correctly after performing
the following corrective actions, contact your nearest YOKOGAWA dealer.
• To verify that the module is operating correctly, perform the self test as described on
the next page.
Probable Cause/Corrective Action
Check to see that the module is installed correctly into the station.
Also, install the module into another slot, and check whether it will
operate there. If it operates in the other slot, the measuring station
is likely to have malfunctioned.
If the module is installed correctly and does not operate, the
connector might be bad or the IC may have malfunctioned. In either
case, contact your nearest YOKOGAWA dealer to have it repaired.
Check whether the "O" indicator on the left of the [Output] button
is green. If the waveform is a trigger oscillation or gate oscillation,
check that the settings are correct.
Check to see that the output waveform setting and output conditions
are correct.
Check that the settings you are trying to enter are within the
specifications.
