Comments
•
The
[:DC]
parameter is optional. Both of the following command statements
select a DC voltage range:
VOLT:DC:RANG <
range
>
or
VOLT:RANG <
range
>
•
To select a standard measurement range, specify range as the input signal’s
maximum expected voltage. The multimeter then selects the correct range.
•
MIN
selects the minimum range available with the
VOLTage[:DC]:RANGe
command:
0.125 V.
MAX
selects the maximum DC voltage range available: 300 V.
•
You must select a range using
VOLTage[:DC]: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[:DC]:RANG
command overrides the range setting from a previous
CONFigure
command on 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 DC range changes the AC voltage range to a corresponding value
(the AC range is
7
⁄
10
of the DC range).
•
*RST Condition:
VOLT:RANG:DC 8.0V
