4. Measuring
2i1 Press to activate the laser.
.. Distance Measurement
Press again to trigger the distance measurement. The measured value is displayed immediately.
ContinuousMeasurement (Tracking) & Max and Min Measurement (See "Figure E")
The continuous measurement function (tracking) is used for the
transferring
of measurements, e.g ., from construction plans. In
continuous measurement mode, the measuring tool can be moved
MIN
to the target, whereby the measured value is updated approx. every
0.5 seconds in the third line. The corresponding minimum and
maximum values are displayed dynamically in the first and second
line.As an example, the user can move from a wall to the required
distance, while the actual distance can be read continuously. For
continuous measurement, push button • until the indicator for
continuous measurement appears in the display. And press MEAS
or Clear button again to stop the function. The function
is terminated
automatically after continuous 100 times measurement. Figure E

** in favorable conditions (good target surface properties, room temperature) up to 10 m (33 ft). In
unfavorable conditions, such as intense sunshine, poorly reflecting target surface
or high temperature
variations, the deviation over distances above 10 m (33 ft) can increase
by ± 0.15 mmlm (± 0.0018 inlft).

B.Measuring Conditions
Measuring Range
The range is limited to 50m.
At night or dusk and
if the target is in shadow the measuring range without target plate is increased.
Use a target plate to increase the measurement range during daylight or
if the target has poor reflection
properties.
Target Surfaces
Measuring errors can occur when measuring toward colorless liquids (e.g. water) or dust free glass,
Styrofoam or similar semi-permeable surfaces.Aiming at high gloss surfaces may deflect the laser beam
and lead to measurement errors.
The measuring time may increase against non-reflective and dark surfaces.
Care
Do not immerse the instrument in water. Wipe
off dirt with a damp, soft cloth. Do not use aggressive
cleaning agents or solutions. Handle the instrument as you would a telescope or camera.
