Calibration (CALIb)
The calibration consists of five menus.
Calibration
[CALIb]
Acting Type
[SINGLE/ dOUbLE]

Auto Calibration 1 [AUTO 1]
Calibration on the zero and end points of the valve
Auto Calibration 2 [AUTO 2]
Calibration on all parameters required to operate the valve
Travel Zero [TVL ZERO]
Manually adjust the zero point of the valve
Travel End [TVL ENd]
Manually adjust the endpoint of the valve
Auto Calibration simplifies calibration without having to go through complex gain tuning. Once the
current input between 4 and 20 mA is applied, it takes approximately 2 ~ 3 minutes to complete the
automatic calibration, which may vary depending on the size of the actuator. There are two types of
Auto Calibrations as shown below so that you select and use them as required.

Acting Type (SINGLE / dOUBLE)
This is used to change the settings of the positioner to SINGLE or dOUBLE, depending on the actuator
type. The setting of the SINGLE and dOUBLE affects the automatic calibration, so it must be set
carefully considering the actuator type.
When the actual acting types of Actuator is different with the setting values, make sure to fit
the actual acting type with the currently operating Actuator type as the certain performance
troubles may incur.
