ZERO button: Short press zeros the display regardless of the position of the blade. Measured angles from this point on are referenced to the displayed value previous to zeroing. For example,if the zero button was pressed while the blade was set to 30°, measured angles after zeroing are now referenced to 30°.

2. Press ZERO button to rezero the display.

REV button: Short press gives you the reverse (miter) angle, with reference to 180°. For example,pressing REV button while the blade is positioned at 45° converts the displayed value from 45° to 135° (180.0° – 45.0° = 135.0°). Pressing the button a second time, toggles the display between the two values. Note “REV” is also shown on display when this feature is activated.
