5.12. SPECIAL SOFTWARE FEATURES
5.12.1. MAINTENANCE MODE SWITCH
Teledyne Instruments analyzers are equipped with a switch that places the instrument in maintenance mode.
When present, the switch is 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 feature is of particular use for instruments connected to multidrop or Hessen protocol networks.
5.12.2. SECOND LANGUAGE SWITCH
Teledyne Instruments analyzers are equipped with a switch that activates an alternate set of display messages
in a language other than the instrument’s default language. This switch is 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. Contact Teledyne Instruments Customer Service personnel for more information.
5.12.3. DILUTION RATIO OPTION
The dilution ration feature is a software option that is designed for applications where the sample gas is diluted
before being analyzed by the Model 200EH/EM. Typically this occurs in continuous emission monitoring (CEM)
applications where the quality of gas in a smoke stack is being tested and the sampling method used to remove
the gas from the stack dilutes the gas.
Once the degree of dilution is known, this feature allows the user to add an appropriate scaling factor to the
analyzer’s NO, NO
2
and NO
x
concentration calculations so that the measurement range and concentration
values displayed on the instrument’s front panel display and reported via the instruments various outputs reflect
the undiluted values.
Contact Teledyne Instruments Customer Service personnel for information on activating this feature.
Instructions for using the dilution ratio option can be found in Section 6.8.1.
