CONFigure:CURRent:AC
Syntax CONFigure:CURRent:AC
[{<range>|AUTO|MIN|MAX|DEF}[,{<resolution>|MIN|MAX|DEF}],](@<scan_list>)
Description Configure the specified channels to the ACI 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, but the resolution is fixed at
6
1
/
2
digits.
<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 to 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.
 If the input signal is greater than can be measured on the selected range, 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.
 <scan_list> overwrites the current scan list.
Example CONF:CURR:AC MAX,DEF,(@121)
CONF?
The query returns "CURR:AC +1.000000E+00,+1.000000E-04".
