    DS440IS 6.10 Double weighing mode DOUBLE WEIGHING options are most commonly used for weighing means of transport, which are weighed prior to loading (entry weighing) and then again after loading (exit weighing) to determine the quantity of goods that are being transported. Double weighing options can be done with: ...

  • Page 84: Entry/Exit Functions With Data Recall

    DS440IS 6.11 Entry/Exit Functions with Data Recall This type of procedure is enabled during the installation phase. The two weighing phases for entry and exit do not necessarily have to be consecutive. The difference between the entry and exit weights can be calculated at the time of the second weighing. 6.11.1 Entry weighing procedures For each entry print-out, the terminal allocates and prints out a code (the RCD code).
  • Page 85 DS440IS The data printed out are:  date  time  progressive number  a product code with details  a client code with its details  plate  RCD code  first weight The data relating to the first weighing operation are held in the memory until the second weight is printed out.

  • Page 86: Exit Weighing Procedures

    DS440IS 6.11.2 Exit weighing procedures The terminal is able to print out the second weight only after the operator has recalled the RCD code of the first weight. Proceed in the following way:  Press key RCD . The last RCD code used is displayed along with the associated data. ...

  • Page 87: Unused Rcd Code Recovery

    DS440IS Printing will take place only if:  the weight stabilises within 10 seconds;  the weight is not negative or over the maximum weight capacity. The data printed out depend on the printer connected or the configuration chosen for the first weighing.

  • Page 88: Entry/Exit Operations Using Licence Plate Data Recall

    DS440IS 6.12 Entry/Exit operations using Licence Plate Data Recall The RCD Plate code is made up of as maximum of 10 alphanumerical characters which the operator enters manually and which must be set before each entry weighing operation. Refer to par. 6.11.1 on page 1-83 and par. 6.11.2 on page 1-85 for the entry/exit procedure. In this case, the reference key is not RCD but PLATE.

  • Page 89: Preset Weight Options

    DS440IS 6.13 Preset weight options The preset weight options are used when the first weight (or tare) of a vehicle is known and therefore does not need to be weighed. The preset weights are associated with a code that can be used to recall them. Besides the preset weight, each code can also store auxiliary information such as the product code or the client code.

    DS440IS 6.13.2 Weighing procedures with preset weights Once the vehicle is on the weighing scales, press the RPD (or PPLATE) key and enter the desired code to recall the first weight preset by the list. The weight on the scales, the preset weight code and the preset weight will appear on the display. Press for a print-out of the weight.

    DS440IS OPTIONS MPP memory expansion boards Terminals provided with the MPP option (permanent weight memory) can memorise the weight data of each individual weighing operation in a permanent memory and transmit the value to an external peripheral along with an identifying code ascribed by the terminal itself. It is possible to check whether the data item is correct by entering the identification code in the weighing terminal.
