Aperture times and sample rates assume a fixed range and autozero off. Reading
rates are for the DC Voltage function. Times and number of readings are approximate.
* IMM is set with SAMPle:SOURce IMM.
Example: Setting the
Aperture Time and
Sample Period
This program segment shows the context in which SAMPle:SOURce and
SAMPle:TIMer are used, and their relationship to the aperture time.
10 !Configure the stand-alone multimeter for DC voltage measurements on
20 !the 7.27 V range. Turn off autozero. Set the aperture time to allow a
30 !sample period of 5 ms. Make a burst of 5 readings, sampled every 5 ms.
40 !Place the multimeter in the wait-for-trigger state and take the readings.
