Peak Current Limit Calibration
For models N6753A through N6756A and N6763A through N6766A, the peak current
limit calibration is valid for five years.
Step 1. Connect only the electronic load or equivalent resistor (up to 500 W rating) across the output
terminals for the first calibration point.

valent, including lead resistance)
N6755A/N6765A Electronic load set to 43.75A, CC mode (0.37 Ω equi-
valent, including lead resistance)

valent, including lead resistance)
Electronic load set to 8.75A, CC mode (8.75Ω equi-
valent, including lead resistance)
Step 2. Select peak current limit calibration.
