Dwyer Instruments DDM-01 Installation And Operating Instructions

The Model DDM-01 Laser Distance Meter offers quick measurement of
distances up to 229.7 feet (70 meters) with the click of a button. It is also
able to easily make area and space calculations and volume measure-
ments from what it records. Another feature of the Model DDM-01 is that
it is able to use the Pythagorean Theorem to indirectly calculate the height
of an object. The meter can read out in feet, inches, or meters and in-
cludes a backlight for use in dark areas.
