Hi,
I am having problems on understanding the computation for PXIe-6570 Force/Measure Current Accuracy.
What comes next after finding the zone (step 6)?
Can anyone give me an example of the computation?
Thanks!

Let me show you an example for calculating accuracy,
Steps
Hope step 7 clarifies your question about how to apply +-1% to get the accuracy number.
Alternatively, if my impedance was 100 ohm and force current was -1.5mA, the voltage required becomes 150mV. Now, the 150mV, -75% lies outside zone1 in the graph and hence there is no warranted accuracy specification (as mentioned in step5)

It makes so much more sense now.
Thank you!
