7.1.3 Acumulation measurement using PLC
► Start the measurement when READY is low resistance.
The MEASURE output is low resistance during the measurement.
After the measurement, the MEASURE output becomes high resistance. If only the
REC STROBE output is high resistance again, you can read out the analogue outputs.
This is the case after approx. 300 ms.
If automatic purging is activated, READY becomes low resistance after purging. Only
then can the next measurement be started.
