HOW TO USE
Measuring conditions
The quality of the measurement depends on the surfaces to which you are
measuring. Strongly reflecting targets deflect the laser beam and cause measuring errors. Non-reflecting, dark surfaces increase the measuring time.
Always begin by making a control measurement.
Measurement errors
Measuring errors are possible in case of:
• Colorless fluids (e.g., water)
• Clean, translucent glass
• Styrofoam or similar semi-translucent surfaces
• Strongly reflecting targets that deflect the laser beam
• Measurements aimed at moving objects
For consistently accurate measurements
• Perform control measurements periodically.
• Perform control measurements before and after important measurements.
Switching on/off
• Switch on the device by pressing Clear/Off
Battery and Measuring Plane symbols until another key is pressed.
• Switch off the device by pressing Clear/Off
key is pressed for 3 minutes, the device switches off automatically.
Clear key
• Undo the most recent action by pressing On/Measure (key 3)
briefly.
