(SEE NOTE 2)
Note 2. More than one device
can be connected as long as
they have differential input and
total input resistance is less
than 500 ohms.
Note 3. The voltmeter is
optional and reads voltage
proportional to the current.
Length of wiring to this terminal
is limited to 1 Meter.
Note 4. Unused channels will
show open loop unless outputs
are shorted as shown for
channel 8.
