*NOTE: There are two signals for each current channel in the disturbance recorder: coarse and ne. A
coarse signal is capable of sampling in the full range of the current channel but suffers a loss of
accuracy at very low currents (< 3 A). A ne signal is capable of sampling at very low currents and with
high accuracy but cuts off at higher currents (I01 peaks at 15 A, I02 peaks at 8 A).
