signals to ensure that the zero and span gas valves will be
controlled synchronously. If you have the –C Internal valve
option—which includes additional zero and span gas inputs—
the 3000T automatically regulates the zero, span and sample
gas flow.
Range ID Relays: Four dedicated Range ID relay contacts. The first
three ranges are assigned to relays in ascending order—Low range is
assigned to Range 1 ID, Medium range is assigned to Range 2 ID, and
High range is assigned to Range 3 ID. The fourth range is reserved for the
Air Cal Range (25%). Table 3-4 lists the pin connections.

At this printing, this port is not yet functional. It is to be used for future
options to the instrument. Pins 13 (+) and 29 (–).
Remote Valve Connections: The 3010TAC is a single-chassis
instrument, which has no Remote Valve Unit. Instead, the Remote Valve
connections are used as a method for directly controlling external sample/
zero/span gas valves. See Figure 3-5.
