Digital Remote Cal Inputs: Accept 0 V (off) or 5-24 VDC (on)
inputs for remote control of calibration. (See Remote Calibration
Protocol below.) See Table 3-3 for pin connections.
Floating input. 5 to 24 V input across the + and – pins put the
Zero:
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.)
Floating input. 5 to 24 V input across the + and – pins put the
Span:
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 synchronous signal must open
