All the settings are never lost even after the battery has been
completely discharged since the instrument uses a particular
MRAM internal storage memory.
Through a data output connector a link can be made to a
dedicated printer or to a computer. This connection can only be
made by using the cables supplied by the manufacturer. With the
printer connection a header and 3 user-customisable lines can be
printed; through the computer link, and with suitable software, it
is possible to control all the functions of the roughness tester,
transmit the measured profile to the computer and enter and
change at will the 3 customizable lines.
The printout, in all the envisaged modes, can only be produced
using the keys on the printer (optional).
