Using Differential Weighing on the DM300M-DM475

Use Differential Weighing to calculate then print the price of each mailpiece as you remove it from the scale.
Products affected: DM300M™, DM400M™, DM475™ (G922, RG9224M)

Differential weighing speeds up the weighing process and increases your efficiency when processing mail. Place all the mail on the scale at once, then remove one piece at a time and run it through the franking machine.  The franking machine calculates and prints the postage for each piece of mail.

Important: Each piece of mail must weigh at least as much as the Differential Weigh Trip Weight that has been set. If you remove a mailpiece that does not meet the minimum weight, the scale does not recognise its removal.

  1. Select the desired carrier, class, mail type, account (if you use the Accounting feature), and Envelope Message.
  2. Press Weight/Rate.
  3. Select Differential Weighing.
  4. Place all the mail on the scale. Use a container, if necessary.
  5. Remove a single mailpiece from the scale, and process it in the normal way.
  6. Continue removing mailpieces and processing until you reach the last mailpiece.
  7. When you remove the last mailpiece or container from the scale, the franking machine asks you if you wish to print postage. Select Yes or No.
  8. You can now place more items on the scale to continue using the Differential Weighing option. Alternatively select Exit Diff. Weighing.
