Experimental Physics and Industrial Control System
|
Greetings all,
I have a question needing rapid response - hence my wasting tech-talk
bandwidth instead of contacting Cosylab directly (which I will do also).
I have a Cosylab BLM system consisting of one of their MicroIOCS and a
Bergoz detector. One of the procedures to follow when first using this
system is a calibration involving setting two trimmer potentiometers.
In the (Cosylab) manual, they refer to setting the output of a
particular detector 'side' to 10KHz - however all of the PVs for that
device talk in "Counts". I'm not sure how to do a proper calibration
when all the software returns are counts per time-slot.
For now, I just changed my time-slot to 1ms (about the longest duration
possible) and adjusted the potentiometers to readback a value of (close
to) 10 (figuring that 10 counts in 1ms = 10,000 counts in 1 second).
This was pretty difficult - I feel as if I am dangerously close to an
'edge' of the trimmer pot and therefore in a non-linear region. Needless
to say, I am not confident I have done this correctly.
Does anyone out there have experience with this system? We have an
opportunity today to do some experiments - hence my somewhat frantic email.
TIA,
--Josh
