5.9.2. Maintenance Mode Switch
API’s instruments can be equipped with a switch that places the instrument in maintenance mode. When
present, the switch accessed by opening the hinged front panel and is located on the rearward facing side of the
display/keyboard driver PCA; on the left side; near the particulate filter.
When in maintenance mode the instrument ignores all commands received via the COMM ports that alter the
operation state of the instrument. This includes all calibration commands, diagnostic menu commands and the
reset instrument command. The instrument continues to measure concentration and send data when requested.
This option is of particular use for instruments connected to multidrop or Hessen protocol networks.
5.9.3. Second Language Switch
API’s instruments can be equipped with switch that activates an alternate set of display message in a language
other than the instruments default language. When present, the switch accessed by opening the hinged front
panel and is located on the rearward facing side of the display/keyboard driver PCA; on the right side.
To activate this feature, the instrument must also have a specially programmed Disk on Chip containing the
second language.
