Dilution-unit 

The dilution-unit, inside the analyser dilute the sample gas flow with a define ratio. 
The unit is preadjusted. The operator must do a fine calibration of the device, to 

improve the accuracy of the measurement. For the fine calibration it is 

indispensable to tubing the vent and all sample gas inlets, before making the actual 

calibration. The correct order for the fine calibration is shown in the flow chart. 

 

 
 

 

 

 

 
 

 

 

 

 

 
 

 

 

 

 
 

 

 

Furthermore, it can be necessary due to abrasion and contamination effects to 

recalibrate the dilution-unit. 
 

9.1.

 

Correct installation of the SWG100 

See chapter 7.5. 
 

9.2.

 

Tubing of all sample gas inlets 

See chapter 7.6. 
 

9.3.

 

Installation of the calibration gas cylinder 

For the calibration of the dilution-unit, MRU recommends a gas cylinder with a min. 

concentration of 500 ppm, from the target gas.
