How many ECHO probes can be excited by one excitation port on a CSI datalogger?
Excitation voltage does not appear to be affected by the number of probes wired into the same excitation port. Thus, you should be able to hook up as many wires as will comfortably fit into the input channel. When connecting multiple wires into one excitation port, care must be taken to ensure that all wires are securely fastened into the wire lug.
