Calibration - Porter Cable RT-7690 Serie Guía Para El Usuario

Calibration

The RT-7690 series laser systems are calibrated before shipment to ensure a
superior product, conforming to the specifications provided. Although it was cali-
brated before leaving the factory, it contains many precision-machined parts that
may be affected if the instrument is subject to abuse. Therefore, if the unit is
dropped or sustains significant impact, check its calibration. It is also recom-
mended that the base unit be periodically calibrated, as a normal maintenance pro-
cedure.
To calibrate the RT-7690 series laser systems:
1. Select a site for calibration that allows the base unit to be placed about 50 ft.
(15m) away from a smooth vertical surface, such as a wall. Use an Allen
wrench to remove the calibration port covers on the side and front of the
unit. Store the calibration port covers in a safe place.
2. Set the base unit on a level surface at one end of the range. Position it with
the side facing the wall. Ensure the calibration port faces away from the wall.
3. Turn on the power
mode (at the shortest line length) for best laser beam visibility. If the
beam is not visible, use the laser detector to locate the beam.
4. Mark the height (center) of the laser beam on the vertical surface of the wall, as A.
5. Rotate the base unit 180°, taking care not to change its height. The base unit
should be positioned with its opposite side facing the same vertical wall as in
step 2. Use the level Line Dither/Scan position arrows
beam on the original wall.
6. Mark the height of the laser beam on the same vertical surface, as B. If B is
positioned at the same height as A, proceed to step 11. Otherwise, continue
to step 7. The goal of the next few steps is to position the level laser beam at
a height halfway between A and B.
7. Turn off the laser beam and power to the unit.
! Caution: The laser beam must be turned off and the main power switch
8. Insert an Allen wrench into the side calibration port and locate the calibration
screw. Rotate it clockwise to lower the beam, or counterclockwise to raise the
beam.
