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 
88 
 -key or the 
 -key to change to the corresponding submenu:
• 
Press the 
88 
 -key or the 
 -key in the line "Used method" to select the parameter and
setup "Splines" or "4th-order polyn."; confirm it with the 
88 
 -key.
• 
Change to the line "Effected range for 4th-order polynomial" with the 
↓↓
 -key.
• 
Press the 
88 
 -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 
88 
 -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 
88 
 -key.
6) Enable the linearization:
• 
Change in the menu "Linearization" with the 
↑↑
 -key or the 
↓↓
 -key to the line
"Linearizer is".
• 
Press the 
88 
 -key or the 
 -key and select "Enabled" with the 
↑↑
 -key or the 
↓↓
 -key.
• 
Confirm your adjustment with the 
88 
 -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
