This is the second time I've received the dial gauge not being zeroed. I returned the first, and on the second I zeroed the arrow with a calibration screw. Attached photos. Otherwise the sensor and accessories are as advertised and offer good value for money.1. The illustration shows the needle not zeroed.2. Remove the rubber shock absorber.3. Rotate and remove the transparent frame.4. Zero with the calibration screw.5. The display pressure gauge is set to zero.
