How consistent is your DAD? If it sits for 24 hours could yours read .03 less? What is your experience? I’m questioning mine. I set an analog angle dial at dead 0 measured 24 hours later and dead 0 that was 41.00 reads 41.03.
usually, pretty accurate, after a period of use you may have to use the calibration system in the owner’s manual but vibration can cause a slight change to reading, and temperature in the area–they are sensitive. .03 the eye cannot detect and is over kill.
