Why are the unused channels on IDERC4 produce unstable spikes?
The IDERC4 unit have high input impedance. As any high input impedance electronic device, the IDERC4 has a very small leakage current (in the order of nano Amps) that can cause these open voltage readings if the input is left open. The unused inputs could be connected to ground of disabled by the software if it bothers. To disable unused channels, go to “Connect” > “View Channels” > and choose the unused channel. Then restart the program. Unused channels are best to disable than to connect the inputs to ground to increase the IDERC4 processing speed.
