Pulser Plus Digitally filters out (ignores) harmonics in your system to measure only the fundamental frequency where ground faults occur Capable <strong>of</strong> measuring and storing more parameters, including both voltage and current monitoring. Analog Unless an actual signal filter is in place to filter out the harmonics, this system is very susceptible to nuisance tripping Typically only measures either voltage OR current, not both, for monitoring. This could lead to an situation where there is a problem with the resistor (open) and the system will not detect it.
