PORTABLE AND EASY TO USE
With small size 60mm*60mm*30mm, you could carry by hand easily.
Simply switch between Absolute and Relative measuring mode.
Green backlight for easy reading in the dark.
HIDDEN MAGNETIC BOTTOM
Magnets hidden make sure it's reliable for measuring meral surface and also avoiding the influence of absorbed metal dust for the accuracy.
INACCURATE DISPLAY WARNING
When the device tilts diagonally over 30 degrees, it will display ERRO instead of an angle. Because in this situation, this angle gauge is not accurate as it shuold be.
1. Why it always show ERROR or ----(no readings)?
MEMS technology provides precise measuring result, but it will not accurate when angle gauge tilts diagonally over 30 degrees. So it tells ERROR or ---- to remind people to use it in a accurate way. Angle gauge with no ERROR indication will not give a correct measurement.
2. Do I need to recalibrate this angle gauge? How to recalibrate it?
GemRed angle gauges are well-calibrated from our factory and lab. You can use it out-of-box. If you want to recalibrate it, please refer to the video in the product page.
3. Does it has magnets on all four sides?
It only has magnets on the bottom. This angle gauge only work with the bottom. Other sides will not give accurate measurement.
4. What's the return policy for this angle gauge?
GemRed provides life-time after-sales services for its products.
