8.10.2 Position Transmitter Zero / End (PTM ZERO / ENd)
ZERO adjusts the zero point of the position transmitter (4mA feedback), and ENd adjusts the end
point of the transmitter (20mA feedback). This is used when the analog output signal needs to be
feedbacked differently than the actual position of the valve, or to be adjusted a little. A measuring
instrument such as an ampere meter is needed to view the analog output signal, and it should be
connected as shown below.
