5)Calculate linearization curve:

·Change in the menu "Linearization" to the menu line "Calculate linearization curve coefficients..." with the -key or the -key.

·Press the 8 -key or the -key to change to the corresponding submenu:

TAG

F4

·Press the 8 -key or the -key in the line "Used method" to select the parameter and setup "Splines" or "4th-order polyn."; confirm it with the 8 -key.

·Change to the line "Effected range for 4th-order polynomial" with the -key.

·Press the 8 -key or the -key to select the parameter.

·Select any of the four ranges or all ranges with the -key or the -key and confirm your adjustment with the 8 -key.

·Change to the line "Start calculation for used method !" with the -key or the -key and start the calculation of the linearization curve with the 8 -key.

6)Enable the linearization:

·Change in the menu "Linearization" with the -key or the -key to the line "Linearizer is".

·Press the 8 -key or the -key and select "Enabled" with the -key or the -key.

·Confirm your adjustment with the 8 -key.

7)Linearization control:

·Repeat the measurement with the same setpoint values used for the linearization curve.

·The full scale deviation has to be better than 1% rel. !

Further Setups and ramifications in the menu "Linearization":

¨Set all raw/setpoint values to 0.0 !

Starting this function will reset all x/y-pairs of raw and setpoint values to zero.

¨Menu Line "Linearization Procedure...":

Via this line you can change to the menu "Linearization Procedure", where you can

·set up gas blender parameters

·set up the valve position

·control the linearization procedure status
