Position Transmitter Zero / End (PTM ZERO / ENd)
PTM ZERO is capable of changing the output current at the origin (4 mA output) of the position
transducer, and PTM End is a function to change the output current at the final point (20 mA output).
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.
