What is Tolerance and how is it calculated?
Tolerance as it relates to the Huntron software can sometimes be difficult to explain but here is our best short explanation. The software samples a single cycle of the applied sinewave regardless of frequency. For signature creation, sine information for both the voltage (horizontal) and current (vertical) are examined but only the horizontal data is used when comparing. We digitize these waveforms by plotting 100 locations across the entire waveform cycle. These points are the byte location. We then look at the location of where the waveform crosses through a particular byte location and assign it a number (referred to as a signature point). This signature point will be positive or negative depending on it’s location within the byte location and can be 0-99*. The tolerance is the number allowed for a compared signature point to be “different”. For example, your tolerance is set to 5. If the STORED signature point in byte location 10 is “20” and a compared signature point for the same
