Quick Guide for General Failures
The general hardware failures are described in the following. Reading the
following information can help in determining the cause of some general
hardware failures:
1. No start-up after pressing the power button:
(1) Check if the power cord is correctly connected.
(2) Check if the power button is operating correctly..
(3) Check whether the fuse has been burned out. If the fuse is blown, please
replace with a fuse of the same rating
(4) Check if the connection between the power supply and the main board.
(5) If the instrument still does not work normally, please contact SIGLENT.
2. Starts up with a dark screen:
(1) Check the connection between the power supply and the main board.
(2) Check the connection between the keypad circuit board and the main
board.
(3) If the instrument still does not work normally, please contact SIGLENT.
3. No response after pressing any button, or abnormal display of the
screen:
(1) Check the connection between the keypad circuit board and the main
board.
(2) If the instrument still does not work normally, please contact SIGLENT.
4. The output voltage amplitude measured is higher or lower than
expected:
(1) Check the connection between the generator and the load.
(2) Check if the impedance set in generator matches the input impedance of
the load.
(3) If the instrument still does not work normally, please contact SIGLENT.
