400 0 0 50 CALIBRATOR DAC
This test steps the calibrator control DAC from 0
to 10volts in 1 volt steps and measures the
resultant output voltage with the system ADC. It
then compares the results with the limits shown to
the left and if outside any limit it will set the error
number corresponding to that voltage level.

600 0 50 50 OFFSET AMP 1
This test steps the sensor input amplifier offset
DAC from 0 to 5volts in 1volt steps and
measures the resultant output voltage from the
first amplifier stage with the system ADC. It then
compares the results with the limits shown to the
left and if outside any limit it will set the error
number corresponding to that voltage level.

800 0 0 50 GAIN AMP 2
This test steps the sensor input amplifier offset
DAC from 0volts to 5volts in 1volt steps, sets
the second stage gain to 1 and measures the
second stage output voltage with the system
ADC. It then compares the results with the limits
shown to the left and if outside any limit it will set
the error number corresponding to that voltage
level.

1000 0 0 50 THRU FILTER
This test steps the sensor input amplifier offset
DAC from 0 to 5volts in 1volt steps, and
measures the filter amplifier output voltage with
the system ADC. It then compares the results with
the limits shown to the left and if outside any limit
it will set the error number corresponding to the
voltage level.
