How can we set the impedance baseline (milliohms) and the alarm threshold for impedance measurements?
A. The impedance baseline is the threshold set by customer and is independent from any other parameter of the system. Typically this value is set based on known impedance of the new battery, for which the user or the manufacturer might have his/her own pre-defined criteria of impedance increase that constitutes a faulty battery. For example, one number we have seen used is 15% of the new battery impedance; e.g., if the new battery impedance is 3.5 milliohms, the impedance baseline can be set at 4.0 milliohms. In this case if any battery in the system recorded in the Measurement log exceed the 4 milliohm threshold, a Major or Minor alarm could be originated. In all of the systems we are shipping now, this impedance alarm reporting function is now disabled, so you will not see this even if you will activate the alarms. We have had number of discussion with different customers regarding their definition of impedance alarms, and we have heard as many different definitions. Since the result
