Zero:
•
Floating input—5 to 24 V input across the + and – pins
puts the analyzer into the Zero mode. Either side may be
grounded at the source of the signal. 0 to 1 volt across the
terminals allows Zero mode to terminate when done. A
synchronous signal must open and close the external zero
valve appropriately. See Remote Probe Connector. (The
–C option internal valves operate automatically).

Span:
•
Floating input—5 to 24 V input across the + and – pins
puts the analyzer into the Span mode. Either side may be
grounded at the source of the signal. 0 to 1 volt across the
terminals allows Span mode to terminate when done. A
