Returns
<NR2>
is the measured output voltage in volts.
Examples
MEAS:VOLT?
might return 5.0011 which would be the voltage measured across
the power supply output in volts.
*OPC
This command con fi gures the instrument to generate an operation complete
message by setting bit 0 of the Standard Event Status Register (SESR) when all
pending commands that generate an OPC message are complete.
The query command places the ASCII character "1" into the output queue when
all such OPC commands are complete.

Examples
*OPC?
might return

to indicate that all pending OPC operations are fi nished.
*PSC
Sets and queries the power-on status fl ag that controls the automatic power-on
execution of SRER and ESER. When *PSC is true, the SRER and ESER are set to
0 at power-on. When *PSC is false, the current values in the SRER and ESER
are preserved in nonvolatile memory when power is shut off and are restored
at power-on.

Arguments
<NR1>
= 0 sets the power-on status clear fl ag to false, disables the power-on clear,
and allows the power supply to possibly assert SRQ after power on.
<NR1>
≠ 0 sets the power-on status clear fl ag to true. Sending *PSC 1 therefore
enables the power-on status clear and prevents any SRQ assertion after power-on.
