Hooking up the ECHO probes backwards will not damage the probes, however the output you read will not be correct. According to our tests with Campbell Scientific dataloggers, the output should not change at all. But, some customers have reported changes in ECHO readings when it is backwards. Thus if you are not finding probe output from 250 mV to 1000 mV with 2.5 V excitation, check to see if the probes are hooked up properly.
