6.13.3. Analog Output Step Test
This test can be used to check the accuracy and proper operation of the analog outputs. The test forces
all four analog output channels to produce signals ranging from 0% to 100% of the full scale range in 20%
increments. This test is useful to verify the operation of the data logging/recording devices attached to
the analyzer.
