  • Page 14 To set the 0% level measurement (4mA) it is necessary that the real level is the one corresponding to the “4mA Distance”; alternatively it is possible to place a target orthogonally to the RPL81 transmitter at a distance equivalent to the 0% level. Wait until the ECO LED fl ashes for at least 30s, press simultaneously P1 and P2, release them and verify that the ECO LED remains turned on.
