    6.3 Hardware check (service) 6.3.1 General WARNING, the manufacturer recommends that you perform a complete hardware check (service) following every component replacement. The hardware check (service) is used to test the main functions of the hardware of the instrument. This is a menu-guided testprogram that performs a self-check of the DR 3900. The user is guided step-by-step through the program.
  • Page 91 A selection list of optional tests is shown. The displayed tests can be individually deselected as required. These are indicated with [optional] in the description of the individual tests under 6.3.5 Tests performed on page It is always recommended to perform the full hardware check.
