Frequently Asked Questions

Can I change the reference point of the Laser measurement?

The laser measurement reference is fixed at the back edge of the LTM1, opposite the laser pointer (where the battery compartment is). It takes into account the length of the body of the tape measure in the reading.

Can I change the unit of the Laser measurement?

Measurements are only displayed in feet and fractional inches. Metric is not available on the LTM1.

How does the laser distance measure part work?

The laser measurement system works by shining a laser beam on a target. The time it takes for the reflection of the beam to return to the tool is used to calculate the distance to the target.

Can measurement work without the red laser beam?

No, the laser is needed to get a measurement.

What are possible reasons why a reading could be incorrect?

  • The laser pointer is unsteady or moving too quickly. To steady the laser, press the back of the tool (the side with the battery compartment) against a flat subject such as the wall or floor.
  • The target is closer than the minimum range of 10 in or beyond the maximum range of 50 ft.
  • The surface of the target is too reflective. You can make a target plate on the surface using tape or a piece of paper.
  • There is too much bright, visible light on the target. Providing shade or creating a dark target plate on the surface can fix this.
  • The target is able to absorb incoming IR radiation and reflects nothing back to the tool. Examples would be plasma TV’s or computer monitors. Again, creating a target plate would be the solution.
  • The target is too transparent to get a proper reading. A target plate will be necessary to get the measurement.
  • The ambient temperature is outside the specified operating range (32ºto 104ºF).

How do I retract the tape measure?

The tape lock release button is on the bottom of the tape measure.
