**A hard reset is for the original BeerBug unit, not the new Brew Perfect hydrometer.
If your Hydrometer is having trouble with calibration, or your readings seem off, you may need to perform a hard reset of your BeerBug. All you will need to do is short the Hydrometer by rubbing a screwdriver or any similar metal object (like a paperclip) along the pins on the inside of the external connector (this is where the temperature probe plugs in, labeled J4). If there are any LEDs on you will see them turn off. Approximately two seconds later, the LEDs should begin to light up. While they are flashing, attempt to do the Blinkup process through the app. First, clear the device settings (remove from WiFi if you're using iOS), and then afterwards proceed to "blink up" your device to your WiFi network. It should proceed to download any new firmware and begin to work properly.
