88 Multimeter Command Reference Chapter 3
:CURRent[:DC]
CONFigure: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 to
accept that input.
• The AUTO option for the range parameter enables autorange and will not
accept a resolution parameter but will default 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 = 10 mA; MAX = 3A
For resolution: See Table 3-1 on page 70 for valid resolution choices for
each range.
• To select autorange, specify AUTO or DEF for range or do not specify a value
for the range and resolution parameters (see next bullet comment). In the
autorange mode, the multimeter samples the input signal before each
measurement and selects the appropriate range.
• To specify the MIN or MAX resolution while autoranging, you must specify the
AUTO or DEF parameter for range and specify MIN or MAX
e.g.,
CONF:CURR:DC DEF,MIN or CONF:CURR:DC DEF,MAX or
CONF:CURR AUTO,MIN or CONF:CURR AUTO,MAX (you cannot omit the
range parameter
DEF or AUTO). This prevents the MIN or MAX resolution
from being interpreted as a range setting.
Example Making DC Current Measurements
CONF:CURR 3,MAX
Function: dc current; range selected: 3A;
MAX resolution: 0.3mA.
SAMP:COUN 3
Take 3 readings; trigger source is IMMediate
by default.
READ?
Place multimeter in wait-for-trigger state and
make measurements; send readings to output
buffer.
