Calibrate the angle sensor every day that you plan to take 1-point
Pythagoras measurements or on days when the temperature
varies considerably.
Use 2-point Pythagoras measurements when possible; they are
generally more accurate than 1-point Pythagoras calculations.
Use the corner hook and corner extension to simplify
measurements.
When working outside, a tripod will help stabilize the Laser
Distance Meter for greater accuracy, particularly when longer
measurements are needed.
Use the self-timer to reduce the vibrations caused by pressing the
button, especially when longer measurements are needed.
9. Care and Handling
This Laser Distance Meter unit is a precision tool that must be
handled with care.
Avoid exposing unit to shock vibrations and extreme temperatures.
Remove the batteries when storing the unit for an extended time
(more than 3 months) to avoid damage to the unit should the
batteries deteriorate.
Avoid getting the unit wet.
Keep the laser unit dry and clean, especially the laser output
window. Remove any moisture or dirt with a soft, dry cloth.
Do not use harsh chemicals, strong detergents or cleaning solvents
to clean the unit.
