EC type-approval certificate no. DK 0199.312
2.2.9 Operator information messages
The weight indicator has a number of general and diagnostic messages which are described in detail in
the user’s guide.
2.2.10 Software version
The software revision level is displayed during the power-up sequence of the instrument.
The approved software version is 1.00.
2.2.11 Totalisation
The indicator can be configured with a totalisation function, adding actual weight display values to the
memory when pressing “M+” key or automatic, if the equilibrium is stable.
The totalised value is a calculated value and shall be marked as such when printed.
2.2.12 Battery operation
The indicator can be operated from an internal rechargeable battery, if this option is installed.
