What tells the user the MultiRAE Pro battery is almost depleted?

• A. Beep sequence every minute
• B. One LED steady
• C. Bottom LED blinking once per second
• D. All LEDs off

Answer: (C)

Understanding how status indicators convey battery life helps you react quickly in the field. For the MultiRAE Pro, a dedicated low-battery signal is shown as the bottom LED blinking once per second. This pattern is designed to grab attention and prompt you to recharge or replace the battery before it drops too low. Other cues don’t reliably indicate a nearly depleted battery: a beep sequence every minute could be a general alert, a single LED steady might just indicate normal operation or a different condition, and all LEDs off means the unit is powered down or has no power at all. So the bottom LED blinking once per second is the clear, specific cue that the battery is almost depleted.
