 sometimes called the VOM (voltmeter, ohmmeter, milliammeter).  It is the best instrument that can measure voltage, resistance and current.  It is generally made of two types: the analog and the digital. Analog Digital  The needle-shaped rod that moves over the scale of a meter.  It is mechanically connected to the moving coil.  It indicates the measured values on the multimeter scale.  makes it possible to select different functions and range of the meter.  makes it possible to adjust the pointer to the zero position of the scale.  a series of marking used for reading the value of a quantity  can have different types of scale, for voltage and current readings the scales have mostly linear which means equal division.  For resistance readings, the scale have logarithmic which means unequal divisions.  Is used to zero-in the pointer before measuring resistance.  is used to connect the circuit to the electrical components being tested
