9.2 When a Failure is Suspected
Necessary Actions
The Autocal function can be set to
on in the AC-INT, AC-VCA,
AC-SYNC, DC-INT, and
DC-VCA modes. However, for
the AC mode, it can be set to on
only when the waveform is a sine
wave. It is turned off when the
Sequence or Simulation function
is selected. However it can be set
to ON in the AC-INT, ACDC-INT
and DC-INT modes and when the
waveform is a sine wave or DC in
case the stand-by state of
Sequence mode (step0). In the
ACDC mode it cannot be set to
ON unless either AC voltage or
DC voltage setting is 0 V.
4.13
Autocal function cannot be used.
Turn the AGC function off.
4.12
Set the remote sensing function to
ON or OFF. 4.11
Enable the external control.
4.18
The external control is disabled in
the Remote state.
Perform the USB eject operation
(4.9) again just in case, and
remove the USB memory.
Reconnect the USB memory and
make sure the file names are
displayed.
Reduce the number of files in a
folder to 500 or less.
Use a FAT32-formatted USB
memory.
In the AC mode, the control
function works to eliminate the
offset voltage (DC component).
When the product is used in the
ACDC mode, switch it to the AC
mode. 3.4.2
If it does not bring much
improvement, adjust the DC
offset. 4.14
