Using the :FETCh? Command during Continuous Measurement with Internal
Triggering
This is the simplest method for exporting measured values.
It is ideal when measurement (tact) time is not limited, and when external synchronization is not needed.
After connecting to the measurement object, wait for twice the measurement time plus the self-calibration time
(about 130 ms) before exporting the measured value.
Using the :READ? Command while Continuous Measurement is Disabled
Use this method to measure (and export) synchronously with the PC or external trigger signal.
Measurement time can be minimized.
