MEASure:VOLTage[:DC]?
Syntax MEASure:VOLTage[:DC]?
[{<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, start a scan and read the readings.
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 MC3232 and MC3264 module, the standard
values of the range: {200mv|2V|20V|150V}.
wherein, MIN=200mV, MAX=150V, DEF=AUTO.
For MC3120, MC3132, MC3164 and MC3324
module, the standard values of the range:
{200mV|2V|20V|200V|300V}, wherein,
MIN=200mV, MAX=300V, DEF=AUTO.
AUTO
<resolution> Numeric
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: Shown in
the Explanationof this section.
0.3ppm×
<range>

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 This command is equivalent to the CONFigure:VOLTage[:DC] command followed by
the
READ? command.
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.
<resolution> is related to the current integration time and range (<range>). The
relations are as shown in the table below.
