What voltage range should the battery-voltage test read on the CSE 102 detector?

The correct voltage range for the battery-voltage test on the CSE 102 detector is 3.5 to 4.0 volts. This range indicates that the detector's battery is functioning properly and providing adequate power for its operations. If the voltage falls below this range, it could suggest that the battery is depleted, potentially leading to impaired performance of the detector. Ensuring the battery operates within this specified range is crucial for maintaining the effectiveness of the device, especially in safety-critical environments like mining, where reliable monitoring of hazardous gases is essential. A battery voltage outside this range could increase the risk of malfunction, thereby compromising worker safety.
