7.3 Adjustment - Span
1. After setting zero point, supply input signal at 20mA (or 4mA) as the end ampere and
check the actuator stroke. If the stroke is too low, the span should be increased. If the
stroke is too high, the span should be decrease.
2. Changing span will affect zero point setting so zero point should be set again after span
has been adjusted.
3. Above two steps are required several times until both zero and span are properly set.
4. After proper setting, tighten lock screw.
