What is the basic 4-20 mA target calibration procedure?
The sensor can be calibrated in about a minute using a 24 VDC power supply, tape measurer and flat reflective target such as a wall or liquid in the tank. To calibrate the 4 and 20 mA set points, attach the calibration wire to the appropriate power supply leg (see manual), and hold the sensor at the desired range to the target until the blue LED blinks.
