SAFETY
Please read the complete safety instructions in
the booklet delivered with this device.
Use extreme caution when the laser beam is
turned on.
Do not let the beam enter your eyes, another
person’s eyes or the eyes of an animal. Be careful
that reections of the beam (on a reective sur-
face) do not strike your eyes.
LASER RADIATION
Class 2, Do not stare into beam
Do not aim the laser beam at any gas that may
explode.

USAGE
REFERENCE POINT
Four different reference points can be used.
Front Middle (screw) Back End-piece
Different reference points can be chosen using
the Reference point / Timer button [10]. The Ref-
erence point setting [a] will be visible on screen.
MEASURING MODES
NOTE
These two operations can be done in all modes
below.
- To undo the last measurement, press the Clear
/ OFF button [12].
- To save the measured values/results, hold the
Records / Save button [11] for 1 sec.
For all Pythagoras measurements the user must
follow the instructions’ order strictly!
We recommend to mount the instrument on a
tripod with tilting head to increase the accuracy
of your measurement.

al distance in the auxiliary display area [g1]. The
mayor display area [h] shows the last distance
measured.

ber of times needed until the Volume Measure-
ment symbol appears on the measuring mode
