Syntax CONFigure:CURRent[:DC]
[{<range>|AUTO|MIN|MAX|DEF}[,{<resolution>|MIN|MAX|DEF}],](@<scan_list>)
Description Configure the specified channels to the DCI measurement function with the specified range
and resolution, but do 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
”.
The standard values of the range:
{200μA|2mA|20mA|200mA|1A}
Wherein, MIN=200μA, MAX=1A, 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 channel 21 to
channel 24 of MC3324), the rules are as follows:
(@121): channel 21 on the module in Slot1;
(@121:123): channel 21 through 23
on the
module in Slot1;
(@121:123,321): channel 21 through 23 on the
module in Slot1 and channel 21 on the module in
Slot3.
None
Explanation  This command is only applicable to channel 21 to channel 24 of MC3324. When
<scan_list> is set to other channels, an error will be generated.
 The CONFigure command does not place the instrument into the “wait-for-trigger”
state. You can send the
INITiate or READ? command with the CONFigure command to
place the instrument into the “wait-for-trigger” state.
 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.
