Published: 2022-07-21 Revised: 2023-06-29
| Term | Definition |
|---|---|
| Deflection PPM | A deflection occurs when the PPM rises above the background PPM by a specific amount, such as 10, 15 or 20 PPM. This indicates a leak may be present. Once a deflection is detected, Chateau Mobile can be configured to mandate a longer monitoring time. |
| Dwell Time | How many ADDITIONAL seconds the tech spends on a component AFTER the sample time is finished IF deflection is found. |
| Manually Entered | Indicates an inspection entered manually rather than electronically captured via Bluetooth by a handheld PDA in the field. |
| M21 Seconds | The total time in which a component was inspected, combining the Sample Time and any Dwell Time, if needed. |
| Sample Time | Measures how long the component was sampled, not counting any additional time associated with a dwell time after a deflection was detected. |
| M21/AVO Why | Why the inspections occurred. This either shows the frequency or special situation. |
