Set-up routine: This routine sets-up the OO 0071. The microcomputer reads the calibrated value out of the
RAM and sends it to the OQ 0071. This device performs the necessary setting (e.g. range).
Output routine: The output routine starts the first (part) measurement. It gives the ADC the start command
to perform the measurement. This routine displays also the previous measurement.
Compute: This routine reads the counter in the ADC interface and makes the necessary calculations.
Measure: The measure routine starts the second (part) measurement. The PM 2519 makes two measurements
for one display result. The measurement is displayed in the output routine.
The sequence of a measurement is: set-up, output, compute, measure, compute, set-up, output, compute etc.
