[{<range>|AUTO|MIN|MAX|DEF}[,{<resolution>|MIN|MAX|DEF}],](@<scan_list>)
Description Configure the specified channels to the DCV 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 between
0.03ppm×<range> and 3ppm×<range>. The
final resolution is decided by the “
Principle of
setting with smaller value
”.
The standard values of the resolution: refer to the
“Explanation”.
0.3ppm×
<range>
<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.
 AAutoranging 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.
 <resolution> is related to the current integration time and range (<range>). The
relations are as shown in the table below.
