Check Product Accuracy

Periodically check the accuracy of the Product.

Level Accuracy

To check the level accuracy:
1. Find a horizontal site that is almost level, preferably a concrete slab, 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 7.

2. Place the Product about 15 cm (6 in) from target
3. Point the forward laser at target
4. Place a mark at the point where the forward laser intersects the target area.
5. Turn the Product 180 ° on its center so that the horizontal laser intersects with target
6. Place a mark at the point where the horizontal laser intersects the target area.
7. Repeat with the Product 15 cm from target
8. Measure the distance between mark
If the distances are the same, the laser is level.
9. If the distances are not the same, subtract the lesser measurement from the greater measurement and divide
by two to calculate the difference of error.
If the distance 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
