I'm trying to read analogue input via RSE connections with floating signal sources (battery device). And the input signal meets all of the following conditions:
The input signal can share a common reference point, GND, with other signals that use RSE.
Your application permits the use of the +/-10V input range.
The leads connecting the signal to the device are less than 3m (10 ft).
It works fine if the input voltage is between -10VDC and 0VDC (or 0.6VDC and 10VDC). But it just gets approximately 0.6VDC if the input voltage is between 0VDC and 0.6VDC.
Everything is OK if reading analogue input via DI connections with floating signal sources or reading analogue output of USB-6008 with RSE mode.
All 8 analogue input channels behave in the same way.
Any ideas? Thanks in advance.
