Home: Device shows 0 / Zero after a few days of measuring

If your device is showing extremely low values or 0 / Zero after a few days of measuring, please go through the following steps: 

  1. Remove any dust / particles from the small air-holes at the bottom of the device. Ensure that the device is placed on a flat and smooth surface with the display facing upwards. 

  2. Replace the batteries, and wait a few days to see if the measurement changes. 

  3. If the device is still not giving you an extremely low / zero reading then look for the serial number on the back of your device. Then contact us here
