Zero-Point (TR_ZERO) and End-Point (TR_END) for Transmitter
TR_ZERO adjusts the zero point of the transmitter (4mA feedback), and TR_END adjusts the
end point of the transmitter (20mA feedback). This is used when output signal becomes
unstable and requires re-adjustment or when feedback output signal and actual stroke need
to be used differently.
