Task 5 Set the zero position
The zero position can be set anywhere within the full-scale range of the device.
Standalone FlexTest SE Controllers:
A. Using the front panel Dial, adjust the Setpoint to move the actuator to
the position you want to assign as zero.
B. Select any control mode that does not use the encoder.
Select Status > Control Mode
Note If the actuator should move after making the change in control modes,
you will need to reposition the actuator, then change to a more stable
control mode.
C. With the actuator in the desired zero position, click <<Auto Zero>>
button on the Offset/Zero submenu.
Select Setup > Disp. > Offset/Zero > <<Auto Zero>>
Automated Controllers:
A. Adjust the Manual Cmd slider on the Manual Command window to
move the actuator to the position you want to assign as zero.
B. Use Control Mode on the Change control modes on the Control
Panel. Select any control mode that does not use the encoder or
Temposonics sensor.
Note If the actuator should move after making the change in control modes,
you will need to reposition the actuator, then change to a more stable
control mode.
C. With the actuator in the desired zero position, click the Auto Zero
button on the Offset/Zero tab (Inputs panel).
Note When you change the device resolution on the Calibration tab, it
immediately changes the resolution of signal values displayed on the
Station Signals, Meters, and Scope windows.
