General Operation

Single distance measurement

1) Switch on the laser beam by pressing the Measure Button.

2) Point the laser dot to the surface to be measured. (Distance is
measured from bottom of the tool).

3) Press the Measure Button once again. The measured distance will
be displayed.

4) Press the Power On/Off Button to switch off.

Continuous measurement

1) Press and hold the Measure Button for 2 seconds to activate
continuous measuring mode. The tool beeps during continuous
measure mode if beeper is turned on.

2) Press the Measure Button again to stop continuous measure.
(It does not matter if the Quick Measure is On or Off. It will always

switch to continuous measurement). During continuous measurement,
the distances are recalculated and displayed about 8 to 15 times per
second, depending upon the reflectivity of the target surface. When
continuous measure is stopped, the last valid distance measurement is
displayed on the result line.

1) The Quick Measure is designed to allow quick measurements by
pressing the Measure Button to switch on the tool and activate the
laser. In this case, measurement is accomplished when the Measure
Button is pressed the second time.

2) It is also possible to use the power button to switch on the tool. In
this case, the Measure Button must be pressed once to activate the laser
and a second time to accomplish a measurement.

Settings menu (to change sound and unit of measure)

1) With the tool switched off, press and hold the Power On/Off Button
for approximately 2 seconds to enter menu mode.

2) Press the Measure Button to switch the beep signal On or Off.

3) Press the Power On/Off Button to access the measuring units
settings.

4) Press the Measure Button repeatedly to scroll through the choice of
units. Available measure units:

mm m in ft yd 1/8 ft 1/16 ft 1/8 in 1/16 in

5) To close the menu, press and hold the Power On/Off Button for
approximately 2 seconds. The tool is switched off and settings saved.

General Care, Safety And Storage

General safety rules

a) Check the condition of the tool before use.
b) The user must check the accuracy of the tool after it has been

dropped or subjected to other mechanical stresses.
c) Although the tool is designed for the tough conditions of jobsite use,

as with other measuring instruments it should be treated with care.

Do not use prisms or mirrored surfaces

Distances can be measured from all stationary targets without a highly
reflective surface, i.e. concrete, stone, wood, plastic, paper, etc. The use
of prisms or other highly reflective targets is not permissible and, if
attempted, may falsify the results.

Calibration Check

It is recommended to occasionally check the calibration of the tool.

1) Select a known measure distance about 1 to 5 meters (3 to 15 ft) that
does not change over time.

2.) Measure the distance 10 times. Calculate the mean deviation from
the actual distance. The measured mean deviation should be less than
the typical accuracy tolerance of

± 1.5 mm (± 1/16 in)

Cleaning and drying

1. Blow dust off the lens.

2. Do not touch the lens with the fingers.

3. Use only a clean, soft cloth for cleaning. If necessary, moisten the
cloth slightly with pure alcohol or a little water.

NOTE

Do not use any other liquids as these may damage the plastic

components.

Storage

The temperature limits for storage of your equipment must be observed,
especially in winter / summer.

Remove the tool from its pouch if it has become wet. The tool, its
carrying case and accessories should be cleaned and dried (at maximum
40°C). Repack the equipment only once it is completely dry. Check the
accuracy of the equipment before it is used after a long period of storage
or transportation.

Transport

Use the original packaging or packaging of equivalent quality for
transporting or shipping your equipment.

CAUTION

Always remove the batteries before shipping the tool.
