Abstract:
A device for use in measuring voltage, phase rotation, and phase difference between two electrical test points, said device comprising:(a) a supplementary test probe adapted to generate a supplementary electrical signal; (b) a supplementary probe module attachable to said supplementary test probe, said supplementary probe module having (i) means for producing a digital representation of said supplementary electrical signal, and (ii) means for transmitting said digital representation of said supplementary electrical signal using electromagnetic waves; (c) a first test probe in operational communication with said supplementary test probe and adapted to generate a first electrical signal; and (d) a meter module attachable to said first test probe, said meter module having (i) means for producing a digital representation of said first electrical signal, (ii) means for receiving said digital representation of said supplementary electrical signal, (iii) means for processing said digital representation of said first electrical signal and said digital representation of said supplementary electrical signal and for forming at least one electrical parameter output signal, and (iv) means for displaying said at least one electrical parameter output signal.
