Paul, Do you have an oscilloscope handy? When doing precision time interval measurements it's useful to take a look at what the counter inputs actually look like. Use a BNC tee and a 1M scope probe (so as not to artificially load the counter input). For pulse inputs it should help you set the

It is NOT the UPS. Same problem when the 5061B is connected directly to the AC Mains. Jeff, Next thing to try is remove one of the internal 24V battery wires of the 5061B (I assume you have NiCad battery option). The sound may be coming from the 5061B deep/float charger. But first try is the
