Table 8-3 Actions When a Failure is Suspected (Continued)
Category Symptom Possible Cause Necessary Actions
Limiter/setti
ng 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.

4.1.1
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.

4.11
The waveform setting is
incorrect.
The mode is not the
Continuous 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.

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
Problem of
Autocal
function The Autocal
function cannot
be turned on. The output mode is
incorrect. 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.

4.13
The waveform setting is
incorrect.
The mode is not the
Continuous mode.
The AGC function is on. When the AGC function is on, the
Autocal function cannot be used.
Turn the AGC function off.

4.12
Problem of
remote
control See "Instruction Manual (Remote Control)" in the optional CD-ROM.
Problem of
external
control
function The product
cannot be
controlled by the
external control
function. The external control
function is disabled. Enable the external control
function.

4.17
The Remote state is set
by the communication
interface. The external control function is
disabled in the Remote state.
