ANALOG OUTPUTS: CURRENT LOOP
To verify that the analog outputs with the optional current mode output are working
properly, connect a 250 ohm resistor across the outputs and use a voltmeter to measure
the output as described in Section 5.9.3.6 and then perform an analog output step test as
described in Section 11.5.8.2.
For each step the output should be within 1% of the nominal value listed in the table
below.
