A tiny bit of fluff on the HED or the hard wire that goes from the HED feedthrough to the HED can dance with -10,000 V on it. The first easy thing to try is to vent, turn off, remove the two front cables that go to the analyzer, open the analyzer door…
I asked this same question to the Agilent tech who was here for our quarterly maintenance. You won't find any documentation and they won't give you any. Apparently, you can brick your instrument if you don't know what you're doing. The scripts are more…
Hi,
you should set your instrument to "user tune" in startup. But plasma correction is intended for a regualr setup. you can try to run it with your "special configuration".
Under "Startup Configuration" change the Ignition Sequence to "user tune…
This is the correct Tune Solution. It should be fine if you dilute it 1:10.
From the information i have, i cannot say why the res/axis is failing.
Best Regards Chris
That's great. From the Home screen do the following:
Click the <Advanced Features> button
Click the <Library Management> button
At the top of this dialog, click on the library in question and see if the spectra are displayed on the bottom of the…
