next the user is asked if the valve is already 
closed. The user has the option of aborting 
by simultaneously pressing the up and Down 
arrow keys or continue by pressing EnTER. 
If continue, the Calibration will proceed to the 
next screen. (See Figure 64).

This is generally a very quick operation, so the 
above screen will appear as 100% Done-Pass. 
If it did not pass, an error message will be 
displayed. The error must be corrected for 
the calibration to pass.

Performing high calibration

7.3.3.5 High position calibration

This calibration method allows the user to 
perform only the upper end of the position 
(100%) without affecting any other parameters 
within the full calibration like the lower end 
position, pressure readings, speed etc. The 
user MuST have completed either the full 
device controlled or full user controlled 
calibration before performing this calibration. 
This calibration is useful in the case where 
after performing the full device/user controlled 
calibration, the user observes drift in the 
position for the upper end over the time due 
to change in temperature, pressure, magnets 
degrading or weakening actuator spring or 
lose valve shaft coupler. The valve must be 
in appropriate position before starting this 
calibration.

Refer to Figure 65

From Calibration Menu, scroll down to “high 
Calib” then press SElECT/EnTER. The lCD 
will display the screen shown in Figure 65. 
This asks the user if they wish to continue. The 
user has the option of selecting “no” or “Yes” 
by using the Down arrow key to switch. If “no”, 
it will terminate the Calibration before even 
starting. If “Yes”, the Calibration will proceed to 
the next screen.

next the user is asked if the valve is already 
opened. The user has the option of aborting 
by simultaneously pressing the up and Down 
arrow keys or continue by pressing EnTER. 
If continue, the Calibration will proceed to 
the next screen. (See Figure 66).

This is generally a very quick operation, so the 
above screen will appear as 100% Done-Pass. 
If it did not pass, an error message will be 
displayed. The error must be corrected for the 
calibration to pass.
