Certificate of EU type-approval no. DK 0199.202 rev.1
Issued by DELTA
2.2.8 Real time clock
If it is available in the instrument, the real time clock can be activated to get printout with day and
time information.
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 1.07 and 1.08.
The software version 1.08 includes possibility of multi-range.
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 if the equilibrium is stable.
Pressing “MR” key displays the total accumulated weight.
Pressing “M+” and “MR” key will clear the totalised value.
2.2.12 Battery operation
The indicator can be operated from an internal rechargeable battery, if this option is installed.
