TE: There are two signals for each residual current channel in the disturbance recorder: coarse
and fine. 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. A fine signal is capable of sampling at very low currents and with
high accuracy but cuts off at higher currents. Table below lists performance of both channels with fine
and coarse gain.
