GDTdirect™ 3.x )*
The GRANULDISK® Documentation Tool, GDTdirect™ 3.x, is an integrated function for
documentation of the potwashing machine’s operating parameters and critical hygiene control points,
HACCP. The function can be utilised in two different ways. The operating data for the 100 most recent
wash programmes can be read off directly in the control panel window. For complete storage of all
historical data, an external computer can be connected to the machine and operating data can be stored
in separate files. The system requirements for the connection of external computers are Windows 2000
or Windows XP.
