Module Resolution 16-Bit (Unipolar Voltage Input)
Unipolar analog signals are converted into
65536 counts ranging from 0–65535 (2
16
).
For example, with a 0–156mV signal range,
78mV would be 32767. A value of 65535
represents the upper limit of the range.
H or L = high or low limit of the range
Module Resolution 15-Bit Plus
Sign(Bipolar Voltage Input)
The module has 16-bit unipolar or 15-bit
+ sign bipolar resolution. Bipolar analog
signals are converted into 32768 counts
ranging from 0–32767 (2
15
). For example,
with a -156mV–156mV signal range,
156mV would be 32767. The bipolar
ranges utilize a sign bit to provide 16-bit
resolution. A value of 32767 can represent
the upper limit of either side of the range.
Use the sign bit to determine negative
values.
H or L = high or low limit of the range
