Ohm testing fuel injectors

[Witsend]

I notice when Ohm testing fuel injectors with a DVOM and setting meter to the lowest scale some car injectors initially start reading much lower OHM than spec and gradually rise to a reading that is within spec, where other car injectors tend to start reading closer to spec immediately. If graphing Ohms , is there a time comparison between a good and a bad injector reaching the proper Ohm spec when the meter is connected to when the meter reaches the peak resistance?

Not all ohm meters use the same voltage output to check resistance so graphing an injector or coil with an ohm meter would differ from one meter to another. It would be far better to check any electrical circuit for voltage and amperage while it is in use. A second problem with this is some ohm meters may use different voltages depending on the range that you have the meter set to. A third problem with graphing resistance of a coil is that not all injectors or coils have the same size windings or use the same size wires.
