Using Three Points (Partial Height); Indirect Measurements With Inclination Sensor - RIDGID micro LM-400 Operator's Manual

micro LM-400 Laser Distance Meter
1. Press Indirect Measurement Button (
the display. The distance to be measured will flash in the symbol.
2. Aim the laser at the lower point (1) and press ON/Measurement Button (
to take the measurement. The measurement will be displayed in first line.
3. Keeping the instrument as perpendicular to the line between the measure-
ments as possible (with the use of spirit level), Press ON/Measurement But-
ton again to measure the distance of the horizontal point (2). The mea sure ment
will be displayed in the second line.
4. Aim the laser at the top point (3), press ON/Measurement Button to take the
measurement. The measurement will be displayed in the third line.
5. The result of the calculation (Distance 1-3) is displayed in summary line.

Indirect Measurements With Inclination Sensor

The inclination sensor measures vertical angles between ± 65° allowing 5 indirect
distance measurement modes. During angle measurement, the instrument should
be held with minimal side to side rotation (± 10° from level) to function properly.
