The GapGun must be held within ±15° of a perpendicular
line from the feature to be measured. The most accurate
measurements are made closest to the perpendicular.
Standoffs can be used to guarantee alignment.
Because the camera is set on a different axis from the
laser, edges can obscure parts of the feature.
Switching the GapGun round will solve this problem.
The laser stripe should be placed at right angles to the feature. Use standoffs to guarantee alignment.
For best performance with surface finish or colour differences always use U series measurement heads—these have
industry leading performance on challenging surfaces.
Always use M series measurement heads for measuring reflective finishes. When using U series light from the laser
can be reflected indirectly off the object back to the camera and return false readings.
