Multimeter Command Reference 103Chapter 3
:CURRent[:DC]?
MEASure:CURRent[:DC]? [<range>|MIN|MAX|DEF|AUTO
[,<
resolution>|MIN|MAX|DEF]] selects the DC current function and allows you to
specify the measurement range and resolution.
Parameters
Comments • To select a standard measurement range, specify range as the input signal’s
maximum expected current. The multimeter then selects the correct range that
will accept the input.
• The AUTO option for the range parameter enables autorange. The DEF option
for the resolution parameter defaults the integration time to 10 PLC.
• The DEFault option for the range parameter will also enable autorange.
The
DEF option for the resolution parameter defaults the integration time to
10 PLC.
• The MIN and MAX parameters select the minimum or maximum values for
range and resolution:
For range:
MIN = 10mA; MAX = 3A
For resolution:
MIN selects the best resolution (the smallest value) for the
selected range.
MAX selects the worst resolution (the largest value) for the
selected range.
• To select autorange, specify DEF for range or do not specify a value for the
range and resolution parameters. In the autorange mode, the multimeter
samples the input signal before each measurement and selects the appropriate
range.
• To specify a MIN or MAX resolution while autoranging, you must specify the
AUTO or DEFault parameter for range as MEAS:CURR:DC? AUTO or
MEAS:CURR:DC? DEF (you cannot omit the range parameter). This prevents
the
MIN or MAX resolution from being interpreted as a range setting and the
resulting command becomes
MEAS:CURR:DC? DEF,MIN or
MEAS:CURR:DC? DEF,MAX (or use AUTO in place of DEF).
