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
1Patented
2Patent pending
3The capacity is sufficient for approx. 500 measurements
(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.

3 Commissioning
The MarSurf PS1 is delivered with the power
supply isolated to ensure that the built-in battery
does not lose its charge if stored for a lengthy
period.
1. Move the reset switch (17) to the right into
the "I" position to make the instrument ready
for operation.
To prepare the power pack:
1. Select the appropriate mains adapter and in-
sert it into the power pack.
To charge the battery:
1. Connect the power pack to the "9 V ="
socket (18) on the MarSurf PS1 and plug it
into the mains socket.
During the charging process, the four bars
in the symbol appear and disappear in
sequence.
Once the power pack has been connected,
measurements can be carried out immediately.
The battery capacity reached in % can be dis-
played at any time (see Section 3.3.1).
The battery will be fully charged after approx.
1 hour, and the instrument automatically
switches from rapid charge to trickle charge.
The MarSurf PS1 is also charged if it is connected
to a PC via its USB interface (15), but the battery
takes longer to charge using this method.
3.1 Charging the Battery
The MarSurf PS1 is powered by a built-in battery.
The power pack supplied can be used for
stationary operation.
The battery should be charged
– if the instrument is being commissioned for
the first time,
– if around 3 months have passed since the
battery was last charged,
– if the symbol is flashing (i.e. the battery
is down to around 15 % of its capacity),
– if no measurement is possible even though
the symbol is not flashing. 7
For charging, only use the power pack
supplied!
If other power packs are used, the
MarSurf PS1 may be damaged and any
warranty will be rendered null and void.
7This can happen after long periods of storage, for exam-
ple.

12 Mahr GmbH, MarSurf PS1
3.2 Setting up the Measuring Station
Practical examples:
– MarSurf PS1 standing on its vee-block bot-
tom or on the vertical adjusters, measure-
ment on level surface or in bore, stylus tip
pointing downwards.
– MarSurf PS1 lying upside-down on its top
surface (three-point support), vee-block
serving as mount, measurement on cylindri-
cal testpieces of up to 1 kg (2.205 lbs), stylus
tip pointing upwards.
Depending on the length of the testpiece,
the drive unit can be moved longitudinally
into the front or rear lock-in position.
3.2.1 Mobile Measuring Station
To set up the drive unit:
1. Carefully introduce the pick-up (5) into
the pick-up holder on the end face of the
drive unit (7), bearing in mind the plug
assignment.
2. Screw the pick-up protection (6) firmly onto
the end face of the drive unit.
Thepick-upprotectionshouldbeused
at all times if possible as it protects
the pick-up from damage.
Exception: When measuring in
small-diameter bores or at points
that are difficult to access.
After a pick-up has been replaced,
the new pick-up should be calibrat-
ed or its correction value set (if this
is already known) (see Section 5).
3. Fit any additional accessories, e.g. for vertical
adjustment – i.e. the mount (8) and one or
both vertical adjusters (9).
4. Place the drive unit in the correct measuring
position by moving it longitudinally and
rotating it. Guide pins on the drive unit help
to find the ideal operating position.

13
Mahr GmbH, MarSurf PS1
– MarSurf PS1 is held vertically; optional end
face vee-block lies on the circumference of a
cylindrical testpiece, the stylus tip contacting
the end face of the testpiece.

14 Mahr GmbH, MarSurf PS1
3.2.2 Stationary Measuring Station
During stationary operation, the MarSurf PS1 can
be attached to the measuring stand (see Fig. 5).
Measuring stands of types ST-D, ST-F and ST-G
can be used.
A mount (6910201) is required for this which is
available as an optional accessory.
To fit the MarSurf PS1 on the measuring stand:
1. Set up the drive unit (see Section 3.2.1).
The pick-up protection is not absolutely es-
sential for operation on a measuring stand.
2. Lay the MarSurf PS1 on its top surface and
put the mount (22) on top of it so that the
mount’s two screws fit into the threaded
inserts on the bottom of the MarSurf PS1.
3. Tighten the two screws on the mount.
4. Introduce the mount’s bolt into the orifice on
the cage of the column and clamp it in place
using the two set screws (on the reverse of
the cage).
5. Align the testpiece and the drive unit using
the adjusting screw (21) so that they are
parallel.
The MarSurf PS1 can be inclined by ± 15°.
6. Rotate the handwheel for height adjustment
(20) to lower the pick-up to the level of the
testpiece.
7. To change the testpiece, the MarSurf PS1 can
be tilted upwards in the mount and locked in
place.
It is essential that the two screws on the
mount and the two set screws are prop-
erly tightened as otherwise the MarSurf
PS1 could come off and be damaged!
