How to copy and paste your serial number

A serial number typed by hand is easily mistyped. Copy it from your order confirmation e-mail instead:

  1. In the e-mail, select the whole serial number and press Ctrl+C to copy it.
  2. In the Register DU Meter window, click Enter your serial number.
  3. Type the user name in User name exactly as the e-mail shows it, or copy it the same way.
  4. Click in Serial number and press Ctrl+V to paste it.
  5. Click Register.
