M100-TAPResistance measurement

Typical Applications

The M100-TAP measures the value of resistance on tap position changers, typically used on high voltage transformers. Each position on the selector has an equal value of resistance so that as the tap position is increased or decreased the value of resistance increases or decreases respectively, The M100-TAP measure the value of this resistance and provides an output proportional to the value of the number of taps selected. The M100-TAP can also be used to measure variable resistance 2 or 3 wire systems.
