•
MIN
selects the minimum range available with the
VOLTage:AC:RANGe
command: 0.0875V.
MAX
selects the maximum range available: 300 V.
•
You must select a range using
VOLTage:AC:RANGe
before specifying resolution.
Also, in order to specify an aperture time of 10
µ
s, you must select a fixed range.
•
Specifying a fixed range disables the autorange mode set by the
VOLT:RANG:AUTO
command.
•
The
VOLT:AC:RANG
command overrides the range setting from a previous
CONFigure
command specifying the same function. With the new range, a new
resolution is also selected. However, this resolution is based on the aperture time
set by
CONFigure
.
•
Changing the AC range changes the DC voltage range to a corresponding value
(the AC range is
7
⁄
10
of the DC range).

*RST Condition:
VOLT:AC:RANG 5.6V

READ?
!Place multimeter in wait-for-trigger state and
make measurement;
send readings to the output buffer.

!Enter readings into computer.
VOLTage:AC: RANGe?
[SENSe:]VOLTage:AC:RANGe? [MIN | MAX]
returns one of the following
numbers to the output buffer.
The present voltage range selected if
MIN
or
MAX
is not specified. Only the ranges
available with the
RANGe
command are returned. For example, if
CONFigure
selects
the 0.63 V range, 0.7 V is the range returned.
The minimum voltage range available with the
VOLTage:AC:RANGe
command
(0.0875 V) if
MIN
is specified.
The maximum voltage range available with the
VOLTage:AC:RANGe
command
(300 V) if
MAX
is specified.
Example
