Hi Snoopy_94,

I posted this problem on the "Test and Measurement" forum a while back, but nobody has come up with a solution so far:

With J1 fitted the PC screen shows about 8.4milliohm. Pressing the TRIM button causes "Process Short Circuit Trim... Frequency: 100Hz" followed 4s later by "process failed". With J1 removed the screen shows about 700Megohm. The TRIM button causes "Process Open Circuit Trim... Frequency: 100Hz" followed 7s later by "process failed".

Any advice would be gratefully received.

Kind regards,
Peter Clark.
