Specifications
OUTP:REL:POL
This command is valid only if the power supply is configured for the optional relay connector.
Programming NORMal causes the relay output polarity to be the same as the power supply output.
Programming REVerse causes the relay output polarity to be opposite to that of the power supply output. If
OUTP[:STAT] = ON when either relay command is sent, the power supply output voltage is set to 0
during the time that the relays are changing polarity. If the power supply is not configured for the relay
connector, sending either relay command has no affect, but the corresponding relay bit STAT:QUES?
changes accordingly.

STATUS SUBSYSTEM
This subsystem programs the power supply status registers. The power supply has three groups of status
registers: Operation, Questionable, and Standard Event. The Standard Event group is programmed with
Common commands.
Status Operation Registers
The bit configuration of Status Operation register is shown in the following table:

CAL = Interface is computing new calibration constants. OC = The over-current protection
operation is ON. OV = The over-voltage protection operation is ON. POL = The relay is in negative
position (set to REVerse). REL = The relay operation is connect (set to CLOSE). WTG = Interface
waiting for a trigger. ONCE = Stepping on dependant upon the ONCE trigger function. AUTO =
Stepping on is depend upon AUTO trigger function. OUT = Output is configured to ON. TTL =
TTL shut down. LSC = The current stepping operation is ON. LSV = The voltage stepping operation
is ON. PARA = Power supply is in parallel operation mode. NU = Not used.
