Table 9-3 Actions When a Failure is Suspected (Continued)
Category
Problem at
The line
output setting
synchronization
cannot be set.
The output on
state cannot be
achieved.
Output-related
The output
problem
voltage does not
come up.
When the
external signal
is amplified on
EXT or ADD,
the waveform is
distorted and
the intended
output is not
provided.
The measured
voltage is
different from
the setting
value.
224
Symptom
Possible Cause
The signal source is not
set to SYNC.
An error message is
on-screen.
The state is the output
off (the OUTPUT key
LED illuminates)
The output voltage is
set to zero.
The external signal
source is not
connected.
The external input gain
is zero.
The output coupling
mode is the AC mode.
Unnecessary items are
set (for example, the
AC voltage setting
remains for the DC
output).
The limiter is activated
(the limiter icon is
displayed).
Necessary Actions
Set the signal source to SYNC and
the external synchronization
signal source to LINE. 4.19
The output cannot be turned on
while there is an error message. If
the protection function is
activated, remove the cause.
9.1.2
Press the ENTER key to clear the
error message. When the message
says "System Locked", cycle the
power.
Press the OUTPUT key to turn the
output on.
Check for the output voltage
setting. 3.4.4, 3.4.5
When the signal source is EXT,
ADD, or VCA, connect the signal
source to the external signal input
terminal, and set the external input
gain appropriately.
4.17, 4.20
In the AC mode, the waveform
may be distorted as the DC
component removal function
works. Use in the ACDC mode.
Check for the setting again. In the
ADD mode, check on the external
input signal and gain setting as
well. 4.20
For a load with lower impedance,
the limiter is activated to make the
output lower than the setting
value. Check on the limiter
setting. 4.1
