OUTP:REL:POL
Do not install or program the Agilent Relay Accessories if the power supply maximum output current
rating (see Table 3-1) exceeds the contact ratings of the relay.
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 option, sending either relay command generates an error.

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 as
described in "Chapter 4 - Status Reporting". The Operation and Questionable status groups each consist of the Condition,
Enable, and Event registers and the NTR and PTR filters.
Status Operation Registers
The bit configuration of all Status Operation registers is shown in the following table:
Bit Configuration of Operation Registers
Bit Position
15-12 11 10 9 8 7 6 5 4 3 2 1 0
Bit Name
NU NU CC NU CV NU NU WTG NU NU NU NU CAL
Bit Weight
2048 1024 512 256 128 64 32 16 8 4 2 1
CAL = Interface is computing new calibration constants; CC = The power module is in constant current mode.
CV = The power module is in constant voltage mode; NU = (Not used); WTG = Interface is waiting for a trigger.
Note See "Chapter 4 - Status Reporting" for more explanation of these registers.
STAT:OPER?
This query returns the value of the Operation Event register. The Event register is a read-only register which holds (latches)
all events that are passed by the Operation NTR and/or PTR filter. Reading the Operation Event register clears it.
