General Operation

Single distance measurement

1) Switch on the device by pressing the ON button.

2) Press the ON button again to activate the laser.

3) Aim the laser do to the surface to be measured, and press the On
button again. The measurement will be shown in the display

4) Press and hold the OFF Button to switch off.

Continuous measurement

1) With the device on, press and hold the ON Button for 2 seconds
until the continuous measure icon appears 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.
When continuous measure is stopped, the display will show:

• Maximumdistance

• Minimumdistance

• Lastdistance

Continuous measure can be useful to find the shortest distance to a
wall or longest distance to a corner as shown.

Clear button

Press the C/OFF button to clear the last reading or command. During
area and volume measures, the C/OFF button clears the most recent
measure, but preserves previous measures.

Change reference

Default measure reference is the back of the unit. Press the MEASURE
REFERENCE button to change to front, center or extended back with
tail as shown on the icon.

The result will be displayed along with the individual measures.
NOTE: The indirect and indirect double measurements are based

upon the Pythagorean principle which requires a right angle (90⁰) for
accuracy. The indirect measure estimate is less accurate if the
measurements do not form a right angle.

Addition and Subtraction

+ The next measure is added to the previous one

- The next measure is subtracted from the previous one
See figure

Storage and Recall of Measurements

The QM55 will automatically store the previous 50 measurements
results.

1) To retrieve these measures: press the clear button (C/OFF)until there
are no measures shown on the screen

2) Press the + button. The Display will appear like the figure.

3) The higher number (up to 50) indicates the most recent
measurement taken.

4) Use the + or – buttons to scroll through the measurements.

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.
