A:The angle gauge uses MEMS sensors for high accuracy. When the gauge is tilted diagonally over 30°, accurate measurement is not possible, so the display shows ERROR or “----”. This prevents incorrect readings and ensures proper use.
A:No. RDINSCOS angle gauges are factory-calibrated and ready to use out of the box. Optional recalibration instructions are available in the video on the product page.
A:Yes. The gauge features strong built-in magnets on all four sides for secure attachment to metal surfaces.
