U, I, P Measurement over RS-232 Interface without VISA
Library
This example will configure the instrument to measure power, voltage and current on
three-phase system 3 x 400V/50Hz and reads the measurements.
/*
* MEASURE U, I, P (wait synchronously)
*
* This example will configure the instrument to measure power, voltage
* and current on three-phase system 3 x 400V/50Hz and reads the measurements.
*
* The time it will take to finish the measurement is 1 s (averaging time).
* The query DATA? does not wait for the measurement to be completed, so it
* would return whatever values are available at a moment. The delay of 2
* seconds gives the instrument enough time to finish the measurement before
* reading data.
