10.3 Storing the measured values in the memory
Your Rugosurf 20 allows you to store more than
1000 measured roughness parameters or 20
measured values with graphical representation.
A navigation through the submenu Files
allows you to activate the memory. Once this is
done, confirm the menu option Enable via EN-
TER to enable/disable the Memory function.
Finally, press the key to get back to the main
menu.
The status bar tells you the number of measured
values stored in the memory, e.g. M:0.
Any stored value can either be cancelled by
selecting Delete or viewed over Show , or the
memory cleared by choosing Reset .
The option Save Profile let you define whether
the roughness parameters alone or together
with graphs must be stored in the memory.
The available space appears in percentage in the
submenu Files. If the memory is full, an error
message tells you that no other values can be
stored unless you clear the memory.
10.4 Calibration
It is advisable to check and calibrate your rough-
ness gauge regularly. The measured parameter
value Ra (or R using a specimen complying with
ISO 12085) must be close to the specified one.
The calibration process is based on the rough-
ness parameter Ra (or R value for ISO 12085).
The reference value (specimen) will be set prior
to carrying out the measurement.
The measuring conditions along with the cut-off
and the number of cut-offs will be previously set
according to the indicated value on the specimen.
So, for example, defined cut-off length will match
0,8 mm and 5 for their number with a parameter
value Ra of 2,97 μm.
To access this menu option and calibrate your
roughness gauge, select Calibration and confirm
via ENTER .
