to select whether the data graph displays in
units of voltages or codes. This affects both the Waveform
Graph and the Histogram Graph. The axis controls can be
switched between dynamic and fixed. When “dynamic” is
switched on the axis with automatically adjust to show the
entire range of the ADC results after each batch of sample.
When “fixed” is used the user can program the axis ranges and
they will not adjust after each sample batch.
CRC Error (17)
This LED icon illuminates when a cyclic redundancy check
(CRC) error is detected in the communications between the

Histogram Graph and Controls(20 & 21)
The data histogram shows each the number of times each
sample of the ADC output occurs. The control toolbar (21) in
the graph allows you to zoom in on the data. Change the scales
on the graph by typing values into the x-axis and y-axis.
