A Word About the Self-Check – LDARtools

The self-check in the phxApp is used to diagnose, anticipate, and correct any problems that may occur with the phx42. This process allows you to verify the health of the unit, transfer logs (limit length), calibrate your filter detection, and report an issue if any operating parameter is out of range.
If using a SpanBox5 with Cal5.0, we recommend performing a self-check monthly. If not, a self-check should be performed daily with the phxApp before calibration.
We are displaying PASSED / FAILED / COMPLETE, but we are storing the actual values for troubleshooting purposes.
All of the following parameters (and more) are evaluated during self-check:
- Glow Disk
- Solenoid
- HPH₂
- Temperatures
- LPH₂Stabilization
- Sample pressure
- Sample PPL
- Probe check
- Combustion PPL
- Combustion pressure
- Pico Amps
- Other failed parameters may show on-screen as “phx42 error”
Once you have performed a self-check in the phxApp, any non-acceptable results for any analyzer are flagged and you are given an opportunity to comment and submit to the LDARtools Customer Portal.
If your phx42 requires an RMA, the diagnosis provided by the self-check will help us return your phx42 as soon as possible.
