Frequently Asked Questions
Why is there black powder on the caliper?
It's graphite lubricant that lets the jaws slide smoothly. Don't wipe it off, and never use liquid lubricant, which stops the sensor from reading correctly.
Does it measure in millimeters?
Yes. Press the mm/inch button to switch instantly.
