I knew that second regulator was hefty but I had never bothered to
read that it was 5A. I don't have the R board and the S board has a
tiny regulator totally unsuited to driving peripherals.
From what I read about your Fluke 115, it can measure DC amps with
autoranging. Page 12 of the user manual shows how to insert the leads
in series with the power to the sensor. Just put the Red lead to +5
and the black lead to the +5 input to the sensor. The sensor ground
connects to Gnd on the R board.
You might be able to measure MIN MAX and AVG as discussed on page 8 of
the user manual. It depends on whether the meter is fast enought to
capture the little spike. But, really, you don't care. Average is
what you want and you deal with the spikes with bulk capacitance.
