Tips

For accurate readings, hold the device steady and allow a few seconds for the measurement to stabilize. Replace batteries when the low-battery indicator appears to ensure continuous monitoring. Periodically check the calibration, especially if the device is used in critical applications. Store in a dry, cool place when not in use.
