The analyzer normally has one inlet and outlet stream carrying gas to all of the transducers at the same time. A second stream can be provided for the following configurations: a. If an external Nitrogen Dioxide (NO2) converter is to be used, a NO transducer will be fitted in the second stream for direct use with the NO2 converter. b. If an isolated dilution gas stream is used for O2/CO2 then a CO transducer can be fitted to the second stream. The standard unit weighs approximately 14 kg (30.9 lbs). When fitted with the extended chassis (required when multiple GFX sensors are chosen) this...

Recommended calibration intervals For optimum performance, it is necessary to routinely check the calibration of all the internal gas transducers within the analyzer. The recommended periods for each transducer type are shown in Section 11.4. This manual provides details of the following: • the requirements for and configuration of calibration ancillaries (e.g. gases) • the setup of the auto-calibration / validation routines • the connection of external solenoid valves (when auto-calibration is used) • the use of the RS232 output and remote initiation of calibration • the use of Modbus or...

Automatic calibration options Two functions are provided when the optional Auto-Cal feature is ordered. These functions are performed on the transducer. • Auto-calibration: Changes the actual calibration curve Auto-validation: Reads the value to determine if it is within the specified tolerance, making no changes to the calibration curve. Each transducer can have up to three sequences of auto-calibration or auto-validation attached to it. To use the auto-calibration/ validation routine, customer supplied solenoid valves will be controlled by discrete wiring to the relays for each of the...
