What I get from the description is that it will read +/- 10V but will withstand +/- 150V for a short period or +/- 75V continuous. Or am I looking at some old data?
Hmm - yea - I was just reading the #'s on the DI-149 I have. I try to keep all the voltages down in the +/-5V range, just 'cause the microcontroller works that way. Most things like temp sensors, pressure sensors, etc etc work in the 5V range. The software makes calibration really easy, so reading the output of the current sensor and graphing it as +/- 300A vs 0>5V is easy to set up.

For something like battery voltage, a simple voltage divider will work to bring it down to an acceptable level for testing.
