I mounted a 1-ohm resistor on the R-sense of an N2825A user-defined head. Also, I had configured 1-ohm R-sense on a DSOX3012T OnfiniiVision Oscilloscope. According to the N2820-97005 (Keysight N2820/1A High-Sensitivity Current Probes) user guide, the current range is from 5uA to 400mA. But, I only got a 54mA when measuring the variety current consumptions. Is there something I missed to set?
