7. 2:+/-/DBL (2 system, 2 directional double range output)
Channels 1 and 2 measure forward direction and reverse direction flows respectively.
Channels 1 and 2 provide high range and low range measurements respectively.
Selectable channel switching based on flow direction or range.
Graphs of flow relative to output current are shown below.
8. SPECIAL (Special Output)
Measures forward direction flow and reverse direction flow up to 20% of forward direction flow.
Current output range is 0.8mA for -20%, 4mA for 0, and 20mA for 100%.
Same current values are output from channels 1 and 2. One range.
Graphs of flow relative to output current are shown below
