Replace battery Easily
1. Just turn the caliper over so the LCD Display is facing down and the slider clamp is facing toward you (down).
2. Using the screwdriver remove the screw. Once the screw is removed, the battery cover on the opposite side will be loose and the battery will easily come out.
3. Insert new battery with plus (+) side facing up. Replace cover, and while holding it in place, reinsert the screw and tighten.
