Mahr MarSurf M 300, Operating Instructions Manual, Page: 11 / 72

Mahr GmbH, MarSurf M 300 and RD 18 7
The "MarSurf PS1 / M 300 Explorer" software
(see Section 10) enables records of the profiles
and meas uring results to be saved and printed.
The MarConnect interface can be used to start
the instrument remotely.
Accessories
The extensive range of accessories for the
MarSurf M 300 and RD 18 enable a wide variety
of applications (see Section 10):
The end face vee­block allows meas ure­ −
ments on end faces of planar and cylindrical
workpieces.
For testpieces such as crankshafts or cam­ −
shafts which are measured in the axial di­
rection, an optional adapter for transverse
tracing is available.
Operating conditions
Storing/transport temperature range:
­15 °C to +55 °C (5°F to 131°F)
Working/operating temperature range:
+5 °C to +45 °C
(41°F to 113°F)
Relative humidity:
non­condensing, 30 % up to max. 85 %
Protection class:
MarSurf M 300: IP42
MarSurf RD 18: IP40
Evaluation
Most of the parameters stipulated in ISO (DIN),
ASME, JIS and MOTIF are available to evaluate
the measured profile (see Section 5.3).
The evaluation conditions can be set, e.g. refer­
ence line and intersection line for material ratio
Rmr (equiv. to tp in accordance with ASME and
JIS), 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 , 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 meas uring record.
Results and settings can be displayed using ei­
ther the metric or the Imperial system of units.
The integrated thermal printer with graphics
support can output entire meas uring records
with characteristic curves and profile diagrams as
well as individual functions, e. g. an individual list
or curve.
The internal USB memory can store up to 30 pro­
files or 40,000 results.
Interfaces
Using Bluetooth technology, the MarSurf M 300
can be connected with various MarSurf RD 18
drive units (see Section 4.3.3). The instruments
comply with Bluetooth specification 2.0.
The MarSurf M 300'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 meas uring results and profiles to be
transferred to the PC for evaluation, e. g. with the
MarWin software MarSurf XR 20 or XP 20.
