*Indicates 1% tolerance (5% otherwise)
With VRC = 4.0 V, close S1. Switch S2 to Pin 2 and measure current
at Pin 2 (IO1). Repeatedly switch VRC between 4.0 V and 0 V until
Pin 2 current changes polarity. Measure the opposite polarity current (IO2).
Calculate: IRO1 = |IO1| + |IO2|.
Switch S2 to Pin 3 and repeat.
Calculate: IRO2 = |IO1| + |IO2|.
