1. When performing a nitrogen pressure test, why is it beneficial to use a temperature-compensated measurement?
2. True or False: In a system evacuation, the "decay test" or "rise test" should be performed after the vacuum pump is isolated from the system.
3. What is the standard recommended duration for a nitrogen pressure test on a system using A2L refrigerants?
4. To verify that a vacuum pump is operating at its "ultimate vacuum" specification, where should the micron gauge be connected for the test?
5. Which of the following best describes Total External Static Pressure (TESP)?
6. True or False: A capacitor can be accurately tested for microfarads while the system is running (under load) by measuring voltage and amperage.
7. True or False: Target superheat is a fixed value (usually 12°F) that does not change regardless of indoor or outdoor conditions.
8. When measuring TESP on a package rooftop unit (RTU), where should the static pressure probes be placed?
9. What physical principle explains why non-condensables move from the system into the vacuum pump during evacuation?
10. True or False: A 20-degree delta T is always a reasonable expectation.
