-The way how to set up the setpoint depends on your actual hardware. To select the direction of the signal (if higher signal means higher force or opposite) you need to know your hardware and adjust the direction in the hwserver.ini file at the [[hwboxsrv|hwserver]] level.
+To adjust the signal for optical probes, a dialogue can be used (accessible via "Adjust sensor" button next to measurement mode selection or from the main menu), assuming that the vertical probe displacement signal is connected to fast input 1 and horizontal probe displacement signal is connected to fast input 2.

+The way how to set up the setpoint depends on your actual hardware. To select the direction of the signal (if higher signal means higher force or opposite) you need to know your hardware and adjust the direction in the hwserver.ini file at the [[hwboxserver|hwserver]] level. You can also temporarily change the directions via Override mode settings dialogue in the [[settings|Settings]] menu.
 The proportional, integral and derivative parameter of the feedback loop can be adjusted, while the integral term has far most impact on the result (and opposite, the derivative one has no impact at present).
+The Z-manual control allows to move with z-piezo actuator when feedback is off. Feedback on button starts the feedback loop, Feedback off button stops it and drives z-piezo to zero. The "Approach", "Move up" and "Move down" buttons can be connected to motors to control the approach, depending on the hardware settings or are left unconnected.
+To run the scan, select some [[scanpath|scan path]], either raster or more fancy and click on the "Scan" button.
