Syntax CONFigure:VOLTage:AC
[{<range>|AUTO|MIN|MAX|DEF}[,{<resolution>|MIN|MAX|DEF}],](@<scan_list>)
Description Configure the specified channels to the ACV measurement function with the specified range
and resolution. This command does not initiate the scan.
Parameters
Name
Type
Range
Default
<range> Numeric
Any numeric value between MIN and MAX. The
final range is decided by the “
Principle of setting
with greater value
”.
For the MC3232 and MC3264 modules, the
standard values of the range:
{200mv|2V|20V|150V}.
Wherein, MIN=200mV, MAX=150V, DEF=AUTO.
For the MC3120, MC3132, MC3164 and MC3324
modules, the standard values of the range:
{200mV|2V|20V|200V|300V}, wherein,
MIN=200mV, MAX=300V, DEF=AUTO.
AUTO
<resolution> Numeric
Can receive any numeric value, but the resolution is fixed at
6
1
/
2
digits.
<scan_list>
Scan
List
One or more channels (only for the multiplexer
channels), the rules are as follows:
(@101): channel 01 on the module in Slot1;
(@101:103): channel 01 through 03 on the module
in Slot1;
(@101:103,301): channel 01 through 03 on the
module in Slot1 and channel 01 on the module in
Slot3.
None
Explanation  <range> is used to set the range. You can select autoranging to allow the instrument
to automatically select a proper measurement range or you can select a fixed range to
set the range manually.
 Autoranging rule: for signals under test that is between 10%*Range and
110%*Range, the instrument automatically selects Range as the current range.
 When <range> is set to DEF or AUTO, an error will be generated if <resolution> is set
to a numeric value, because the instrument cannot calculate the integration time
accurately (especially when the input signal is continuously changing) when the
autoranging is combined with a numeric resolution. If your application requires
autoranging, be sure to specify "DEF" for <resolution> or omit the parameter.
 If the input signal is greater than can be measured on the selected range (manual
ranging), the instrument gives an overload indication: "OVERLOAD" from the front
panel or "±9.9E+37" from the remote interface.
 The
*RST command will clear the scan list and set all the measurement parameters to
their factory settings. The Instrument Preset (the
SYSTem:PRESet command) will not
clear the scan list; however, this command will clear the data in the reading memory.
 The reading resolution of the ACV measurement function is fixed at 6
1
/
2
digits. Setting
the resolution will not affect the measurement rate. You can control the measurement
rate by modifying the channel delay (the
ROUTe:CHANnel:DELay command) or the AC
filter type (the
[SENSe:]VOLTage:AC:BANDwidth command).
 <scan_list> overwrites the current scan list.
