ISO7637-2 specifies waveform verification for Pulse2b under no-load and 0.5Ω load conditions. The load for verifying the BP-4610 waveform is 06-00060A, which is 1Ω. Why is it 1Ω instead of 0.5Ω?

The Us of Pulse2b is 10V. Measuring with a 0.5Ω load results in 10V ÷ 0.5Ω = 20A, which exceeds the 10A current capacity of the BP4610; therefore, measurement is performed with a 1Ω load.
