Possible Cause
Necessary Actions
Measurement
function-
related
problem
The measured
value fluctuates.
The signal source is set
to EXT.
In EXT, the measurement cycle is
fixed, and thus the difference
from the external signal cycle
may fluctuate the measured
value. On the other hand, in the
ADD mode, the appropriate
measurement cycle is decided
according to the internal signal
source frequency setting.
Therefore, if you know the
frequency of the external signal
to use, change the signal source
to ADD, set the internal signal
source frequency to the external
signal frequency, and set the
internal signal source output
voltage to zero.
A low frequency (less
than 10 Hz) is set.
For a frequency lower than 10
Hz, the measurement cycle is a
fixed value and thus the
measured value may not be
stable.
Limiter/
setting range
limitation-
related
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.
Remote
sensing
problem
The Remote
sensing function
cannot be
turned 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.
The waveform setting
is incorrect.
The mode is not the
continuous output
mode.
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.
The waveform setting
is incorrect.
The mode is not the
continuous output
mode.
The Autocal function is
on.
When the Autocal function is on,
the AGC function cannot be
used. Turn off the Autocal
function.
