Zero-Point (TR_ZERO) and End-Point (TR_END) for Transmitter
TR_ZERO adjusts the zero point of the transmitter (4 mA feedback), and TR_END adjusts the end
point of the transmitter (20 mA 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.
