Purpose

The Lambda transmitter LT3 in connection with the combination probe KS1D is developed for simultaneous measurement of O2 concentration and oxidizing gas elements (CO/H2), displayed as COequivalent in exhaust gases of combustion plants within hyperstoichiometric ranges (λ > 1).
The display and handling of the LT3 is managed via user interface inside the front door (belongs to standard delivery), with the following functions:
- Display of O2 and COe measurement values
- Password entry
- Informationen about probe and fuel, for warnings and failures, for software versions, CRC and serial number
- Calibration of measurement
- Setup (maintenance, filter time, analogue output, probe exchange, display)
