Use of the Digital Multimeter

You should be familiar with the DMM, particularly the essential tool J 39200, the digital multimeter. You should be able to use the multimeter to measure voltage (volts), resistance (ohms), current (amps), capacitance (farads), intermittents (min/max) and frequency (hertz).
