Resistance is defined as the impeding, slowing, or stopping effect exerted by one material thing on another. Before we talk about electrical resistance it is important to understand that on a vehicle that there are 2 types of resistance you will run into (Pun intended)....
A quick check of available voltage at an automotive battery would show you around 12.6v. No need for a graph to show a static number. However, if checking to see how much voltage signal is being returned from a throttle position sensor (TPS), a graph would be quite helpful. This voltage signal would likely travel upward vertically from 0vdc to 5vdc as the pedal
Depending on the type of circuit and operational health of that circuit an ohm measurement can be variable (Thermistors, etc...), non existent (or very very low) or visible but not expected. With the ability to give live readouts and graph resistance measurements you are able to see the resistance value of a circuit or component immediately (live) and in its past in relationship to time. Although this seems obviou
The ability to compare readings from N2 units for either channel to channel comparisons, relationships OR variances which when applied to temperature testing can easily turn your N2's and mobile application into the hvac testing tools of choice beyond testing of electrical measurements, dropouts and glitches.
The application for the N2 is something that will constantly be evolving. As the the feedback and user experiences continue to pour in, highly needed and desired updates will be provided to the app including functional testing assistants, comparative measurements between devices, logging and sharing of data within the built in community, interactive learning and teaching modes along with training resources and much more.
