Measurement Errors
Error messages will appear if the unit’s receiver is not getting a
sufficient laser return signal.
Common surfaces that could cause an error reading:
- Water or other fluids
- Translucent to clear surfaces like glass or acrylic
- Porous or dark surfaces may require longer reading times or
cause an error reading
- Moving surfaces or objects such as curtains
- Highly reflective or angled surfaces may deflect the laser
beam signal

into smaller segments.
Err04 Pythagorean theorem calculation error Check and verify value or the
sequence of measurements
is correct
