problem
The output
current
peak-hold value
(measured) is
larger than the
peak current
limiter setting
value.
The output current
overshoot occurred for
the limit value.
While the peak current limiter is
activated, the overshoot may
occur depending on the load.
4.1.1
Remote
sensing
problem
The Remote
sensing function
cannot be set to
on.
The output mode is
incorrect.
The Remote sensing 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 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.
4.11
The waveform setting is
incorrect.
The mode is not the
Continuous mode.
The mode is not the
stand-by state of
Sequence mode.
In the stand-by state of
Sequence mode (step0)
and ACDC mode either
AC voltage or DC
voltage setting is not
0 V.
The Remote
sensing function
cannot be set to
FB.
DIP or RIN is not
connected.
Connect this product and DIP or
RIN.
8.2
External control
function is set to Disable
or Enable.
Set external control function to
DevCtrl.
4.18.2
Problem of
AGC
function
The AGC
function cannot
be turned on.
The output mode is
incorrect.
The AGC 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.
4.12
The waveform setting is
incorrect.
The mode is not the
Continuous mode.
The Autocal function is
on.
When the Autocal function is on,
the AGC function cannot be used.
Turn off the Autocal function.
4.13
The remote sensing
function is set to FB.
Set the remote sensing function to
ON or OFF.
