uct from Mahr GmbH. We kindly request that
you follow the instructions below in order to
ensure the continued precision operation of the
instrument over the long-term.
We operate a policy of continuous improve-
ment and are constantly developing our prod-
ucts, especially with regard to renaming of type
designations. It is possible therefore that there
may be slight differences between the text and
illustrations in this document and the product in
your possession. We reserve the right to make
changes to the design and scope of supply, the
right to undertake further technical develop-
ments, and all rights relating to translation of this

Permitted Uses
The MarSurf PS1 roughness measuring instru-
ment must only be used for measurement and
evaluation of roughness.
The MarSurf PS1 roughness measuring instru-
ment can be installed both close to production
areas and in inspection rooms.
Do not modify the instrument. This may create
additional hazards that cannot be sufficiently
protected by the safety mechanisms.
The operating, maintenance and repair require-
ments specified in these operating instructions
must be followed.
Disposal
Electronic devices, including accessories and used batteries (rechargeable
and disposable), must not be disposed of as regular garbage, since they
contain high-value materials that can be recycled and reused. European
Directive 2002/96/EC (WEEE) requires that electrical and electronic de-
vices must be collected separately to unsorted municipal waste so that
they may be subsequently reprocessed. The crossed-out garbage can
symbol indicates that separate collection is necessary.
Mahr GmbH carries out the redemption and disposal of its electrical and
electronic products in accordance with legal requirements. Please contact
your local service representative.

cians. Disconnect the power supply before replacing the battery.
12. Only Mahr-trained personnel are permitted to carry out work on this instrument and its compo-
nents. 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 operating instructions will void the equipment warranty. Mahr GmbH declines all liability for
damage caused by unauthorized procedures.
13. Do not use fluids on or near the instrument and its components.
14. Do not use cleaning materials that contain harmful substances. Do not use solvents.
15. Inspect the connecting cables at regular intervals and check for damage. Change damaged cables
immediately (Mahr service personnel).

1 Functions
The MarSurf PS1 is a compact roughness meas-
uring instrument for mobile use under shopfloor
conditions.
The maximum measuring range is 350 µm
(0.014 in) (-200 µm to +150 µm) (-0.008 in to
+0.006 in).
With the built-in drive unit, measurements can be
performed in any measuring position without the
need for setup times. The maximum traversing
length is 17.5 mm (0.700 in). The instrument
is easy to use and complies with DIN EN ISO
3274.
The MarSurf PS1 and all Mahr pick-ups are bal-
anced at the factory. For high-precision measure-
ments using the stylus method and subsequent
checks, an automatic dynamic calibration func-
tion is available. A standard is integrated in the
MarSurf PS1 for this purpose. 1
PHT pick-ups have an innovative open skid 1that
virtually eliminates deposits of dirt and oil.
The bow-type vertical adjusters 2allow many dif-
ferent forms of support (stable three-point sup-
port, four-point support, e.g. for cylindrical test-
pieces, combination with the pick-up protection,
etc.) and makes vertical adjustment very easy.
The rugged housing makes the MarSurf PS1
ideal for operation under severe conditions. The
instrument combines an ergonomic design with
clearly arranged operating elements and a spe-
cially designed easy-to-read LCD.
Its compact form and low weight (approx.
400 g / 0.88 lbs) make the MarSurf PS1 ideal
for mobile use. Thanks to the carrying case with
shoulder strap and belt loop, it is easy to carry
around. The built-in rechargeable battery offers
enough capacity for several days’ work 3.
The instrument’s power pack comes with three
exchangeable mains adapters, allowing the
instrument to be connected directly to the mains
all over the world.
All the functions supported by the instrument
are set out in a logically structured catalog. The
arrow keys are used to select and set the re-
quired functions from this catalog.
Instrument settings can be blocked and also
protected against unauthorized modification by
means of a code number.
The operator can switch between ISO (DIN), JIS,
ANSI/ASME and MOTIF standards to select the
traversing length and for evaluation purposes.
When measurements are performed in accord-
ance with ISO (DIN), JIS or ANSI/ASME, the
recorded profile is filtered with a phase-correct
profile filter (Gaussian filter) complying with DIN
EN ISO 11562. A shorter cutoff can also be se-
lected for this purpose.
Even inexperienced users can perform correct, re-
producible roughness measurements thanks to
an automatic function. If this function is active,
theinstrument detectsperiodic andaperiodicpro-
files and automatically sets the standard cutoff
and associated traversing length in accordance
with DIN EN ISO 4288. 1

(depending on the traversing length)

6Mahr GmbH, MarSurf PS1
Most of the parameters stipulated in ISO (DIN),
JIS, ANSI/ASME and MOTIF are available to eval-
uate the measured profile (see Section 4.4).
Theevaluationconditionscanbeset,e.g.reference
line and intersection line for material ratio Rmr,
symmetrical or asymmetrical intersection lines
for peak count RPc, operators A and B for the
MOTIF evaluation, and intersection lines for zone
widths CR, CF and CL.
In order to monitor tolerances, tolerance limits
can be set for all selected parameters. If limits are
exceeded, this is indicated on the display (and in
the measuring record).
Results and settings can be displayed using either
the metric or the Imperial system of units.
The internal memory can store up to 15 profiles
or 20,000 results.
The MarConnect interface allows an external
printer (e.g. the Mahr MSP2) to be connected.
This printer can be used to print out both the
entire measuring record and individual measur-
ing results.
The MarSurf PS1’s USB interface allows it to be
connected directly to a PC. It is treated like a USB
memory stick and detected without a driver.
This allows measuring results and profiles to be
transferred to the PC for evaluation, e.g. with the
MarSurf XR 20 evaluation software. Additional
evaluation options allow flexible management
and documentation of measuring results.
From MarSurf PS1 V1.01 onwards, the "MarSurf
PS1 Explorer" software (see Section 10) enables
records of the profiles and measuring results to
be saved and printed.
The software also serves to copy profile and re-
sult files from the MarSurf PS1 to a computer in
a straightforward way.
Thanks to its extensive range of accessories, the
MarSurf PS1 has a wide variety of applications
(see Section 10):
– For testpieces such as crankshafts or cam-
shafts which are measured in the axial di-
rection, an optional adapter for transverse
tracing is available.
– The optional end face vee-block allows
measurements on end faces of planar and
cylindrical workpieces.
