Working Mechanism:

• Fix this crack gauge over the selected crack with the unit's vertical zero line (on the calibration scale) parallel to the monitored crack.
• Make sure that the unit's monitoring spigots (pointed down) are on the crack's right side.
• Use screws and an adhesive to fix the crack gauge and remove the four pre-set pegs.
• The unit's cursor moves relative to the calibration scale if the crack closes or opens. Users should record the crack's opening or closing on the record sheet.
