7.3.4 Distorted Output
7.3.5 No Output and no lights on front panel
7.3.6 No output, but front panel controller is active.
7.3.1 Excessive Output Voltage
CAUSE SOLUTION
External sense not connected(If used) Connect external sense wires on the rear
panel from TB1-1 to TB1-2 and from TB1-
3 to TB1-4
7.3.2 Poor Output Voltage Regulation
CAUSE SOLUTION
Unit is overloaded Remove overload
Unit is programmed to wrong voltage
range.
Select correct voltage range.
Input line has fallen below spec. limit. Check input supply voltage.

7.3.3 Overload Light is On
CAUSE SOLUTION
Unit is overloaded Remove overload or check CL setting
Unit is switched to high voltage range. Select correct voltage range.
7.3.4 Distorted Output
CAUSE SOLUTION
Power source is grossly overloaded. Reduce load
The crest factor of the load exceeds 3:1. Reduce load current peaks by reducing
load.
7.3.5 No Output and No Lights on Front Panel
CAUSE SOLUTION
Input switched off. Switch unit on.
No input power. Ensure power is present at AC input
terminal block.
Incorre
input. Check position of voltage selector
switch on rear panel.
ct input voltage 230V applied to a unit configured for 115V
7.3.6 No Output But Front Panel controller is active
CAUSE SOLUTION
“OUTPUT ON” button is turned off. Press OUTPUT ON so that “ON” LED is
lit.
Current limit programmed down or to zero. Program current limit higher.
Voltage programmed down or to zero. Turn amplitude control up.

7.4 Self test
A self test can be performed over the bus by sending the *TST? query command. The self-test will run
until the first error is encountered and terminate. The response to the query will either be the first
0 if no error was found. (Self-test passed).
To execute a self-test, the IEEE-488, LAN or USB interface must be used. The iXCGui command selftest
window can be used to send the *TST? Command. See the section 9 for possible self test error
es.
