Working Advice

General Guidelines

During Measurement

• Keep lens clear — The reception lens and laser outlet must not be covered
• Hold steady — Do not move the device during measurement (except continuous mode)
• Use support — Place the device against a firm surface when possible

Tip

For best accuracy, press the back of the device firmly against a wall or corner when measuring.

Factors Affecting Range

The maximum measuring range depends on:

Factor	Effect
Ambient Light	Bright sunlight reduces range
Surface Color	Dark surfaces reduce range
Surface Texture	Rough/porous surfaces reduce range
Surface Angle	Steep angles reduce range

To extend range in difficult conditions:

• Shade the target area
• Use a laser target plate
• Measure during lower light conditions

Factors Affecting Accuracy

Surfaces That May Cause Errors

Surface Type	Issue	Mitigation
Transparent (glass, water)	Beam passes through	Cover with opaque material
Reflective (mirrors, polished metal)	Signal too strong	Cover or angle device
Porous (insulation, fabric)	Inconsistent return	Use solid backing
Structured (rough stone, mesh)	Multiple returns	Find smooth area
Angled	Reduced signal	Measure perpendicular

Environmental Factors

• Temperature gradients — Air layers with varying temperatures can bend the laser beam
• Indirect reflections — Nearby surfaces can cause false readings
• Vibration — Movement during measurement reduces accuracy

Accuracy Verification

To verify your device is measuring accurately:

1. Select a test distance

   • Use a known distance of 3-10m (10-32ft)
   • Indoor location with weak backlighting
   • Smooth, light-colored target (white wall)

2. Perform test

   • Measure the same distance 10 times
   • Record each measurement

3. Evaluate results

   • Calculate the average
   • Individual readings should not deviate more than ±2mm from the average
   • Keep records to compare accuracy over time

Note

Periodic accuracy checks help you identify when calibration may be needed.

Using a Tripod

For professional work and longer distances, a tripod is essential.

Setup

1. Mount the device using the 1/4”-20 thread on the bottom
2. Secure firmly to the tripod
3. Change reference point — Long press + to set reference to “tripod” (middle)

Benefits

• Eliminates hand shake
• Consistent measurement position
• Required for Pythagoras modes
• Enables precise leveling using angle display

Quick Tips

Situation	Recommendation
Measuring corners	Use rear reference, press firmly
Long distances	Use tripod, target plate
Bright outdoors	Shade target, use at dawn/dusk
Multiple measurements	Use continuous mode for MIN/MAX
Complex spaces	Use Pythagoras for indirect
Professional work	Always use tripod
