Reconnect the load resistor.
Switch on the power supply.
Decrease the load resistance (current rises) and set it for an output current of
approximately 9.5A.
Decrease the load resistance and the voltage output should drop, indicating that
current limiting is in progress.
If the power supply is very hot, the current limit circuit may cause the unit to
switch off completely. If this occurs, switch off the mains supply and wait
approximately one minute. The power supply should now operate normally.
