Command summary
The measurement commands are used to acquire readings. You can use these high-level
instructions to control the measurement process. These commands are summarized in Table 15-1.
Configuring measurement function
This topic provides detailed information on commands that can configure the measurement
function.
CONFigure:CURRent[:DC]
Query :CONFigure? Returns active function (current).
Description This command configures the instrument to measure DC current. The :READ?
command is then typically used to trigger a specified number of measurements.
See “READ?,” page Section 15-4.
When this command is sent, the Model 6482 will be configured as follows:
• Select current function.
• All controls related to the current function are defaulted to the *RST values.
• The event control source of the trigger model is set to Immediate.
• The count values of the trigger model are set to one.
• The delay of the trigger model is set to zero (0).
• All math calculations are disabled.
• Buffer operation is disabled.
• Autozero is enabled.
• Both source outputs will turn on.
WARNING When :CONFigure is sent, the outputs will turn on. Beware of hazardous
voltage that may be present on the output terminals.
NOTE This command is automatically asserted when the :MEASure? command is sent.
