With a nitro/gas powered helicopter you can simply rotate the clutch or engine crankshaft by hand until the signal generator (magnet or similar) passes the sensor. Whenever the signal generator is within the detection range of the sensor the Status-LED should light up in blue color.
In addition to the function control of the sensor, check the throw setting for the throttle servo in the remote control and adjust if necessary: Set the throttle to mid stick position and attach the servo horn, so that the throttle linkage is at a right angle to the servo horn. Then adjust the length of the linkage according to the instructions of the helicopter, so that it also is positioned perpendicular to the linkage lever at the carburetor. Adjust the lever at the carburetor so that it is opened halfways (note the markings on the carburetor!). Now move the throttle stick towards full throttle and adjust the servo travel in the transmitter accordingly, so that the full throttle position is reached without binding. Lastly move both throttle stick and throttle trim on the transmitter to the „motor off“ position and also adjust the servo travel in that direction until the carburetor is fully closed. If the servo travel must be greatly reduced in both directions, it is recommended that the linkage ball on the servo arm is mounted further in so that the servo can be moved over a wider range. For more information refer to the instruction manual for your helicopter.
If the Status-LED on the AR7210BX does not light up as described please double check the wiring. Particularly pay attention whether the power wires of the sensor are of correct polarity (on some sensors the wire colors do not match the usual standard!). If you have a magnetic sensor check if the magnets are installed with the correct polarity and if they are passing the front of the sensor close enough. Using a crankshaft sensor make sure that the sensor is mounted close enough to the frame accordingly.
