phx42 FID Probe Integrity Testing
What is a probe integrity inspection?
A probe integrity inspection is used to identify leaks too small to be detected during the probe block step of the self-check.
It involves connecting an ignited phx42 to a supply of zero air and running an alcohol-based wipe along the whole length of the probe, while watching the handheld for deflection.
When should a probe integrity inspection be performed?
The best practice is to conduct a probe integrity inspection every week and/or
anytime you have a drift/calibration failure or suspect a probe problem.
A probe integrity inspection is NOT…
- A visual inspection
- Blocking the probe tip
- Swapping a suspected leaking probe with a “known” good probe
When should I use a Probe Testing Adapter?
You should use the Probe Testing Adapter (LDAR#4300) when a filter error is not resolved by following the on-screen prompts during a self-check.
