Care ................................................................................................ 11
The compact and handy base model was specifically designed for
indoor application professionals. Shortcut and Soft grip keys for addition,
subtraction, area and volume calculation make measuring fast and very
reliable. Moreover, the NT-6560 with Pythagorean Theorem calculation
performs various indirect heights.

SAFETY INSTRUMENT
Permitted use
Measuring distances
Computing functions, e. g. areas and volumes
Indirect Measuring with Pythagorean Theorem
- 1 -
Prohibited use
Using the instrument without instruction
Using outside the stated limits
Deactivation of safety systems and removal of explanatory and
hazard labels
Opening of the equipment by using tools (screwdrivers, etc.), as far
as not specifically permitted for certain cases
Carrying out modification or conversion of the product
Use after misappropriation
Use of accessories from other manufacturers without the express
approval of PROKIT'S INDUSTRIES CO., LTD.
Deliberate or irresponsible behavior on scaffolding, when using
ladders, when measuring near machines which are running, or near
parts of machines or installations which are unprotected
Aiming directly into the sun
Deliberate dazzling of third parties; also in the dark
Inadequate safeguards at the surveying site (e.g. when measuring
on roads, construction sites, etc.)
Laser classification
The NT-6560 produced a visible laser beam which emerges from the
front of the instrument.
Laser Class 2 products:
Do not stare into the laser beam or direct it towards other people
unnecessarily. Eye protection is normally afforded by aversion
responses including the blink reflex.
WARNING:
Looking directly into the beam with optical aids
(e.g. binoculars, telescopes) can be hazardous.
- 2 -
Precauti
Do not look directly into the beam with optical aids.
Looking into the laser beam may be hazardous to the eyes.
Precautions:
Do not look into the laser beam. Make sure the laser is aimed above or
below eye level.

the measuring tool can be moved close to the target,
whereby the measured value is updated approx. every
0.5 seconds. The corresponding dynamically maximum

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
