instrument has to make a range selection).
— If you select auto ranging (by specifying "AUTO" or "DEF"), an error will be generated if you specify a
discrete value for the <resolution> parameter. When auto ranging is combined with a discrete
resolution, the instrument cannot accurately resolve the integration time (especially if the input signal
is continuously changing). If your application requires auto ranging, be sure to specify "DEF" for the
<resolution> parameter or omit the parameter from the command.
— Auto range thresholds:
Down range at:
Up range at:
— If the input signal is greater than can be measured on the selected range (manual ranging), the
instrument gives an overload indication : "OL" from the front panel or "±9.9E+37" from the remote
interface.
Examples
The following program segment configures the instrument for AC voltage measurements. The READ?
command places the instrument in the "wait-for-trigger" state, triggers a measurement, and then sends
the reading to memory and the instrument output buffer. The default range (auto range) and resolution
(5½ digits) are used for the measurement.
