6.9.3. 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.
To begin the Analog Output Step Test press:
SAMPLE RANGE = 500.000 PPM CO2 =X.XXX

Pressing the key under “0%” while performing the test will
pause the test at that level. Brackets will appear around
the value: example: [20%] Pressing the same key again
will resume the test.
