3. Measuring
Important
•
Measure against a hard, even surface and make sure that the area between the meter and
the measured surface is free from obstructions to enable the most accurate readings.
•
Distance can be measured from the front or back of the device or by using its fold-out reference pin.
•
If you need to measure the distance to a surface which is soft, irregular or too small, place a
piece of cardboard in front of the surface.
•
The laser beam may not be used to measure through glass surfaces. Reflections from such
measuring may be faulty due to reflections.
