Setting the measurement range
When simultaneously sourcing and measuring either voltage or current, the measure range is
coupled to the source range, and you cannot independently control the measure range. As a result,
you do not set the range when testing voltage or current measurement accuracy.
When selecting the source range, be sure that the limit is set to the appropriate maximum value for
that range.
Taking the Model 2461 out of a limit overflow state
Calibration verification measurements should not be made when the Model 2461 is in a limit overflow
state. For purposes of the calibration verification tests, the Model 2461 can be taken out of an
overflow state by raising the limit value.
Do not take the instrument out of an overflow state by decreasing the source value or changing the
range. Always use the recommended range and source settings when verifying the instrument.
Remote calibration verification procedure
Use the following procedure to verify instrument calibration by sending SCPI commands over the
IEEE-488, USB, or LAN connections.
Step 1. Prepare the Model 2461 for calibration verification
Verify that the calibration verification environment, instrument, and test equipment are set up as
described in
Preparing for calibration verification and adjustment
(on page 2-1).
