Lots counting errors at using the DDCSV with MPG

arco

Dear Madam Dear Sirs,

I bought the DDCSV2.1 from you. And connected it with a MPG (Handwheel).

The precision was set for MPG to 0.005, if I move the handwheel
slowly or fast it gives me not a continous incrementing or decrementing
of the counters on the display.

- set precision to 0.005
- Counter incrementation on display
+0.005
+0.006
+0.005
+0.004
+0.002
+0.005
+0.005
+0.002

and not what is required, like this:
+0.005
+0.005
+0.005
+0.005
+0.005
+0.005
+0.005
+0.005

I replaced also the MPG and used also other precision.
The result is same bad, the countin is not continous.

Seems there is somewhere a bug or wrong. Please help me to
fix the error of this DDCSV2.1, else I can not use it.
