There is also a frequency function, just the thing for troubleshooting fuel-injection or ABS problems, and an audible continuity tester. If you really like to dig into the electrical innards, you can use the meter's capacitance, duty-cycle and diode test functions. On the bells-and-whistles side, the meter is auto-ranging, meaning that it automatically selects the best range for accurate measurement. The LCD screen is large and easy to read -- a real blessing for my tired old orbs. There is also a data-hold feature, which freezes the screen, and an auto power-off to save the batteries.
