the value.

 

 

 

 

 

 

 

 

 

 

When the Prot annunciator is on, press

to see which protection circuit caused the power supply

 

to shut down. Response can be OC (overcurrent), OT (overtemperature), or OV (overvoltage). If no

 

 

protection circuit has tripped, the display will show dashes (- - - -).

 

 

 

 

 

Press this key to reset the protection circuit. If the condition that caused the circuit to trip has been

 

 

removed, the Prot annunciator will go off.
