Machine thinks plasma is on
Hi everybody
we have recently received an 720 ICP OES. After moving it worked. Took a bit of time to repair the ASX520 sampler-this one works fine now-but the machine thinks the plasma is on-but for sure it is not.
So I checked the Ar flow-that is fine. Rebooted the machine and the computer-same issue. Disconnected the power line for some minutes-same issue.
Looked at the computer board and tried reset-issue remains.
The inside of the machine looks full of dust so I will clean it and renew some corroded fuses and clean some corroded earth points.
Anybody an idea what causes the problem of plasma is on? Is there a switch that is telling the machine that the plasma is on?
By the way anybody got a diagnostic password?
I am more familiar with Perkin Elmer ICP-MS the Agilent/Varian machine is new to me.
Have fun
Thomas
