The Automode L,C,R is the most accurate mode to determine DUT component, and by using this option, the approriate parameter set is automatically selected. Select AUTO mode (AM sign appears at the top row of the display) for automatic measurement of inductance, capacitance, or resistance. In the AUTO mode, the Smart Tweezer uses 1 kHz test frequency by default and has limited sensitivity. Automatic detection may not work for small value capacitors and inductors. In this case, 10 kHz test frequency must be used.
