1. Zero position is the range of values over which the transmitter zero can be adjusted. Span is the range of shaft rotation or stem travel the transmitter span can be adjusted. For example, a
zero position of 45 degrees and a span of 15 degrees means the transmitter output is 4 mA DC after 45 degrees of shaft rotation. The output then increases from 4 mA DC to 20 mA DC as the
shaft rotates from 45 to 60 degrees.
2. Refer to figures 15, 22, and 23 for locations of connections.
