Dear K. Don,
We found that the coaxial cable has a problem and it already fixed but we still found something abnormal so please see details what I did.
In remote mode.
-New short hall probe was replaced in the 12” electromagnet (we just received from Lakeshore today) then I did to verify the correct hall probe data is being used.
-Turn on software and let standby for 3 hrs then to do full calibrations.
Moment offset calibration was working properly, after calibrated that found gauss meter was reading 0.0 gauss (normal)
Gauss meter offset calibration was working properly, after calibrated I was trying to make a field to zero by using software it appeared that gauss meter was reading to 0 gauss (normal)
AP calibration , found gauss meter was reading unstable it has fluctuated to positive & negative gauss and also powder supply has generated signal the current output to (+/-) when I applied field to 5000 Oe.
I had replaced the coaxial cable & a spare 736 controller and then repeatable it appears that it still has the same problem.
Please assist.
Adisorn.
