Abstract: A method of safe to mate testing includes providing a file of netlist signals where each signal defines a first connection to one or more components of a unit under test, connecting a first terminal of a measuring device to a first netlist signal and connecting a second terminal of the measuring device to a second netlist signal, performing a plurality of first resistive measurements by applying power having a first polarity between the first and second netlist signals, performing at least one second resistive measurement by applying power having a second polarity to the first and second netlist signals, and recording an average of the first resistive measurements and, if the second polarity measurement yields a negative result, an indication that a reactive load is connected between the first and second netlist signals.
