Calibration - MICRO-EPSILON NLS3181 Betriebsanleitung

Operation
5.2
Every measuring channel must be calibrated for the installation environment and the target prior to measur-
ing. The two potentiometers are set for calibration.
- Turn the potentiometer in a clockwise direction to effect a positive change in the output voltage.
- Turn the potentiometer in counterclockwise direction to effect a negative change in the output voltage.
- Use the original measuring environment for calibration where possible. Simulate the measuring environ-

The measuring system operates. Connect the analog output with an oscilloscope.
Shift the zero point with the potentiometer "zero" until you get a symmetric output signal, see
