WebNote that the AC method shows different values to the DC method when measuring a reactive resistance, and both readings are correct. For example, Li-ion in an 18650 cell produces about 36mOhm with a 1,000Hz AC signal and roughly 110mOhm with a DC load. Since both readings are valid, yet far apart, the user must consider the application.

A calculator for interconverting these frequency and wavelength values is provided on the right.
WebTo get the best results possible, remember to: Know your IR thermometer's distance-to-spot ratio, and get close enough to the target so your thermometer reads only the area that you want it to measure. Watch out for (and compensate for) shiny, "low emissivity" objects. Remember that steam or dust can affect the accuracy of IR thermometers.
