The components of the Corner Crack Monitor
can be reconfigured so that cracks at the
junction of ceilings and walls or floors and
walls can be monitored.
The Corner Crack Monitor is used to
monitor two dimensional movement.
(Ensure the scale and cursor plate are
fixed on the side of the crack which is
moving.) Corner Crack Monitors are used in pairs
and designed to monitor three-dimen-
sional movement.
