Hi,
With our (very) old Oxford 300, we have an HLM2 helium level meter that insists the magnet is at 94% (even if unplugged from the probe). Does anyone have a pinout/test method/manual for the meter (I feel better testing the meter than directly checking resistance on the helium probe itself).
It should read 100% at 0 resistance, so having it unplugged from the helium probe and reading 94% would suggest a problem with the meter itself, but I'd like to be able to check/diagnose.
Thanks,
David
