V.
READ?
!Place multimeter in wait-for-trigger state and
make measurements;
send readings to output buffer.
enter statement
!Enter readings into computer.
VOLTage[:DC]:RANGe?
[SENSe:]VOLTage[:DC]:RANGe? [MIN | MAX]
returns one of the following
numbers to the output buffer.
The present voltage range selected if
MIN
or
MAX
are not specified. Only the ranges
available with the
RANGe
command are returned. For example, if
CONFigure
selects the 0.91 V range, 1.0 V is the range returned.
The minimum voltage range available with the
VOLTage:DC:RANGe
command
(0.125 V) if
MIN
is specified.
The maximum voltage range available with the
VOLTage:DC:RANGe
command
(300 V) if
MAX
is specified.
Example

!Query multimeter to return the present
range.

!Enter value into computer.
VOLTage:NPLC
[SENSe:]VOLTage:NPLC <

sets the integration time in power line cycles
(PLCs). Values are rounded up to the nearest number of PLCs shown in the
following table.

Comments
•
MIN
selects 0.0005 PLCs.
MAX
selects 16 PLCs. Setting the integration time in
PLCs also sets the aperture time and the resolution. For example, 16 PLCs (60 Hz
line frequency) sets an aperture time of 267 ms. The corresponding resolution
depends on the function and range you select.
•
The
VOLT:NPLC
command overrides the results of previously executed
VOLTage:APERture
and
VOLTage:RESolution
commands (the last command
executed has priority).
