is
<Voltage/Current> , the set point unit must be V, mV, A or mA.

Entry Enter the maximum flow controller flow. This is the expected flow
when the flow controller’s
<Max Set> occurs.

All molbox supported gases are selectable in this list. Select a gas
then enter a
<K Factor to N2> (see immediately below) for all
gases supported by the flow controller. The <K Factor to N2>
information is stored for every gas entered. 1 is used by default for
all gases not specifically set up.
