During extinguisher inspection, what should the gauge or indicator show?

Explanation:
The gauge shows whether the extinguisher has the correct pressure for operation. During inspection you want the needle to sit in the operable range (the green zone). This confirms there is enough pressure to discharge the agent when needed and that the extinguisher is ready for use. If the gauge indicates overcharged or undercharged, the unit may not function properly and needs service; if the gauge is broken, you can’t rely on the reading and the extinguisher should be serviced or replaced.
