Check Product Accuracy
Periodically check the accuracy of the Product.
Horizontal Laser Accuracy
To check the accuracy of the horizontal laser:
1. Find a horizontal site that is almost level that is ≥4.57 m (15 ft) wide with two opposing walls to use as targets.
You can also use scrap wood as targets. See Figure 8.
Figure 8. Horizontal Laser Accuracy
2. Put the Product about 15 cm (6 in) from target .
3. Aim the horizontal laser at target .
4. Put a mark at the point where the horizontal laser intersects the target area.
5. Turn the Product 180 ° on its center so that the horizontal laser intersects with target .
6. Put a mark at the point where the horizontal laser intersects the target area.
7. Repeat with the Product 15 cm (6 in) from target .
8. Measure the distance between mark and mark on target and mark and mark on target .
If the distances are the same, the laser is within calibration.
9. If the distances are not the same, subtract the lesser measurement from the greater measurement and divide
the result by two to calculate the difference of error.
If the distance of error is ≤3 mm at 10 m (1/8 in at 30 ft), the laser is within calibration accuracy. If the Product
is not within accuracy, contact Fluke. See How to Contact Fluke.
