Menu 
 
 Latching: A TTL logic signal at the external Remote Inhibit input 
latches the output in the shutdown state; when the output is turned 
off, it is programmed to zero volts, and the output relays are opened; 
this state could only be cleared by the remote digital interface 
SCPI command, OUTPut:PROTection:CLEar; 
 Live: The output state follows the state of the external Remote 
Inhibit input, turning the output on/off. 
 Low/High: Selects the logic level of the Remote Inhibit signal that 
would cause the output to be turned off: either a logic low or 
contact closure, or a logic-high or open circuit.    
 Off: The power source ignores the external Remote Inhibit input. 
AMBIENT STATUS  Configures the Ambient led status feature to turn on/off.
