Safety instructions
This height measuring instrument complies with the relevant safety regulations.
It was dispatched from our production facility in a perfect condition. However,
failure to follow the instructions given below can cause personal injury or death:
1. Before you connect up and use the measuring instrument for the first time,
please read the accompanying documentation.
2. Only use the instrument in accordance with this quick guide.
Keep the documentation close to the place of use ready for quick reference.
3. This instrument is not designed for operation in explosive environments.
An electrical spark could trigger an explosion.
4. Follow safety precautions, accident prevention regulations, and internal
company guidelines. You should request further information from your
company safety officer.
5. Only the AC adapter provided with the device should be used for charging
the internal rechargeable battery or supplying power to the device when
used in stationary applications.
6. Before you connect up the equipment, check that the power supply voltage
marked on the type plate of the AC adapter matches that of the local mains
power supply system. Do not under any circumstances connect the AC
adapter if the voltage is not the same!
7. Only use the AC adapter in enclosed areas.
8. The instrument may only be connected to a properly grounded protective
contact socket. Any extension cables must meet the stipulations of the VDE
(German Association for Electrical, Electronic & Information Technologies).
9. Only Mahr-trained service personnel are permitted to carry out work on this
instrument. Protective covers must only be removed by trained technicians
and only when servicing is required. Any procedures carried out on this
instrument that go beyond those tasks described in the quick guide will
void the equipment warranty. Mahr GmbH declines all liability for damage
caused by unauthorized procedures.

10. Do not use cleaning agents that contain harmful substances. Do not use
solvents. Do not allow any fluids to penetrate the instrument.
11. Inspect the connecting cables for damage. Change damaged cables
immediately (Mahr service personnel).
12. Never move the height measuring instrument forcefully at the edge of the
measuring plate. The air cushion at the edge does not dissipate quickly
enough to slow down the movement of the height measuring instrument.
Itcould fall off the plate and injure the user.
13. The height measuring instrument must only be transported in its original
packaging. Otherwise the warranty will be void.

1 General information
The Digimar 817 CLT is an electronic height
measuring instrument used for measuring and
evaluating lengths, distances, and diameters.
It allows you to safely perform measurements
and calculation functions, as well as create
measuring programs to automate recurring
measuring steps.
The Digimar 817 CLT height measuring
instrument is operated via a swivel and tilting
control panel with touchscreen and features
fast measurement function keys as well as
a thumbwheel, which allows convenient
positioning of the measuring slide.
The user interface of the height measuring
instrument offers clearly structured menus
and large buttons with self-explanatory icons
to ensure quick and fluid processes.
The handles on each side and the integrated
air bearing ensure that the instrument can
be moved precisely and effortlessly on the
measuring plate.
The height measuring instrument comes in
three sizes: 350mm, 600mm and 1000mm.
It enables one-dimensional measurements
in a vertical direction and two-dimensional
measurements if the workpiece can be
tilted90°.
Measuring data can be backed up both
wirelessly and by wired connection using the
MarConnect duplex interface.

2.6 Thumbwheel
The thumbwheel is used to quickly move and
position the probe in a positive and negative
direction.

Thumbwheel
The travel speed corresponds to how far away
the thumbwheel is from its central position, i.e.
the further up the thumbwheel is moved, the
faster the probe moves in a positive direction.
2.7 Button for air bearing
An air bearing can help you position the height
measuring instrument precisely by ensuring
that it moves accurately and effortlessly on
the measuring plate.
There is a button fitted on the handle of the
height measuring instrument to activate the
