The voltage from the solenoid outputs is nominally 0 V for the OFF
and 15 V dc for the ON conditions. The maximum combined current that
can be pulled from these output lines is 100 mA. (If two lines are ON at the
same time, each must be limited to 50 mA, etc.)
If more current and/or a different voltage is required, use relays, power
amplifiers, or other matching circuitry to provide the actual driving current.
Note that each individual line has a series FET with a nominal ON
resistance of 5 ohms (9 ohms worst case). This can limit the obtainable
voltage, depending on the load impedance applied. See Figure 3-9.

Testing the System
After The Control Unit and the Analysis Unit are both installed and
interconnected, and the system gas and electrical connections are complete,
the system is ready to test. Before plugging either of the units into their
respective power sources:
