Indoor & Outdoor Measurements
This model is designed to take measurements indoors under normal settings. The measuring surfaces and ambient light are critical factors to the quality of measurement (indoors and outdoors). Outdoor measurement capability may be limited due to sunlight/UV ray interference. Please note that in some situations the unit may have difficulty reading the surface you try to measure if lighting or sunlight is intense and/or the surface being measured does not reflect the laser beam appropriately.
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
Error Codes and Solutions
| Code | Description | Solution |
|---|---|---|
| Err01 | Distance is outside of measuring range | Measure in a shorter distance or longer distance |
| Err02 | Reflected signal is too weak | Measure a better surface |
| Err03 | Out of display range | Maximum Value: 99,999. Split up measurement area into smaller segments. |
| Err04 | Pythagorean theorem calculation error | Check and verify value or the sequence of measurements is correct. |
| Err05 | Low Battery | Install a new battery. |
| Err06 | Temperature is outside of working range | Measure in an environment within specified working temperature range. |
| Err07 | Ambient light is too strong | Measure in a darker place (shadow target). |
Tips from the Pro's
Take more than one measurement in critical situations where accuracy needs to be greater than an estimation measurement. Take 3-4 measurements from the same position to compare consistency of each reading.
Prior to important measurements, verify that the instrument is in proper working order and take sample measurements to a known distance to verify accuracy.
To accurately measure from the rear of the instrument, use a scrap piece of drywall or other flat material. Extend the material off the corner and butt the LDM up to the material. Then take the measurement.
Place a white sheet of paper over the targeted measuring surface if error message Err02 occurs to improve the return signal.
