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
Measure Back...
