• Calculate the maximum offset distance and compare
to D .

• If D is not less than or equal to the calculated

maximum offset distance the tool must be returned
to your Stanley Distributor for calibration.

• You will need at least 1,5m (16ft ) of floor space and

possibly an assistant for this check.
• Place the laser unit on a level flor and turn on all
K

beams.
• Measure exactly 0.91 m (3ft )from the center of the
K
3
laser unit along the vertical beam of the laser cross. To
easily reference the center of the laser unit start the
and the first measurement againsts the front edge of the laser
1
unit, measure out 0.91 m (3ft), and then subtract 30mm
(1.18in). Mark this point P
• Measure exactly 1.22 m (4ft) out from the center of the
instrument along the 90 vertical reference beam, and
then subtract 30mm (1.18in). Mark this point P
• Measure from P
0.75mm (5ft ±1/32 in). .
• If D is not less than or equal to the calculated
1
maximum offset distance the tool must be returned
to your Stanley Distributor for calibration.
• Repeat these steps as needed, to recheck the
measurements .
