Control diagram
Fig. 6:
Via the parameters (T0 – T6), the times for the valve control are set.
By changing the interval times (T6 – T1), the frequency can be
changed.
times for maximum throughput:
While maintaining the times illustrated in the figure "Control
diagram" and an interval time of 0 ms, the maximum frequency
(15 Hz or 800 cycles/min) will be reached.
This corresponds to a throughput of approximately 4 ml/min with a
set maximum stroke volume.
recommended times for maximum accuracy:
For dosing with the highest accuracy (Tolerance and reproducibility)
≤ ± 2%), the following times are recommended:
