Abstract
Systems and methods for dissipating heat generated during an electrical function are disclosed. In particular, the disclosed systems and methods can be used for dissipating heat generated during low impedance measurement on a multimeter. In some embodiments, the multimeter can include a first thermistor coupled in series with a resistor in a measurement path, a second thermistor, and a switch coupled to the measurement path and the second thermistor for selectively including the second thermistor in the measurement path during a low impedance measurement.
