What is the default startup mode for the MultiRAE Pro?

• A. Normal Mode
• B. Fast Mode
• C. Power-Save Mode
• D. Calibration Mode

Answer: (B)

Starting up the MultiRAE Pro hinges on how quickly the sensors can reach stable readings and how the device manages power during that initial phase. Fast Mode is designed to bring the instrument into a usable state as quickly as possible, so you can begin monitoring almost right away. This makes it the best default choice when speed matters, such as in urgent field situations. The trade-off is primarily in how the device balances power use and initial sensor stabilization, but it ensures you have access to readings without a long wait.

If you needed a slower startup to save battery or to emphasize sensor stabilization before reading, Normal Mode offers a middle ground, while Power-Save Mode reduces energy use at the expense of a bit more time to become fully ready. Calibration Mode is reserved for sensor calibration tasks rather than regular startup.
