Technician A says that a micron gauge is a better indicator of vacuum than a gauge calibrated in inches of Hg. Technician B says that the service valve cores are normally removed before evacuating the system. Who is correct?
A. Neither Technician A nor B
B. Technician B
C. Both Technicians A and B
D. Technician A
Homework Answers
Option c : Both Technocian A and Technician B
Micron gauge can measure vacuum more precisely to smaller values than a gauge in inches of Hg. So, micron gauge is better than Hg gauge in inches.
Hence, Tecnician A is correct.
Removal of service valve cores helps in better and faster evacuation. Hence, Tecnician B is also correct.
So both Techinicians' statements are correct.
