Tip: Mettler Toledo scales used in the European market require a different protocol than when you use them in the United States. To configure Aloha software versions 188.8.131.52 and higher to use the European protocol, edit the Aloha.ini file in the Newdata folder, and assign the MettlerFormat variable a value of 1, such as MettlerFormat=1. Assign a value of 0 for the standard or U.S. protocol.
