The transmitter requires a DC 24 V supply, acceptable range 22 V to 26 V.
Mount the transmitter using the two φ4 mounting holes on both sides, fixing it to the wall with the supplied expansion screws.
After checking that the wiring is correct, connect DC 24 V and use a multimeter to measure the current output.
It is recommended to calibrate the transmitter at least once a year.
