Hi, when I power on my Headspace 7697A it's show this message "vial EPC SHUTDOWN to restore operation press Vial and on", but when I press "Vial" and "on", the problem showing again
Hello again, I took my sample probe and there is not clogged but, the HS still show me the message "vial EPC SHUTDOWN to restore operation press Vial and on", and the restriction and pressure decay test still failling in the first step. How do I can check where is the problem?
It's failing in the step 1 "vent CLOSED (INJECT)" in the guide you linked me says:
"If the test fails this stage, check:
• The sample probe
• A leak causing no restriction value"
I don't have problems with my sample probe, I checked and there is not clogged. I looked for leaks, and I didn't find it.
Is it failing during the very first step or later in the leak and restriction test? There are six steps total in the test, so knowing exactly where it fails in the test will help us narrow the possibilities. The guide I linked previously lists some potential causes for each step (pages 11-17).
Disconnect the sample probe from the valve and start the leak and restriction test.
If it passes this step, it means that there is some restriction in the sample probe, enough to cause that part of the test to fail. Try a brand new probe.
If it fails again, note the pressure and flow values that it gives. That can help figure out what is happening.
