Do the 661xC and 663xB Series power supplies have more than 1 current measurement range? What is the current measurement resolution? How do I switch between them?
Yes, these models feature two 16-bit current measurement ranges. Refer to the illustration that shows Current Measurement for each high range which covers the full output, with an LSB ranging from approximately 20 uA for 1A output to 436 uA for the 10A output.
All models have a low range of 20.0 mA full scale, with an LSB of 0.6 uA. You can select either the high or low range, or autoranging between the two. With autoranging, range switching is triggered whenever the current crosses above/below 20.0 mA.
