Calibrator is a device which is used to calibrate other instruments. Calibrators vary in form and function depending on the instruments with which they are designed to work. The process of adjusting an instrument to meet those specifications is referred to as calibration. Multimeters are often digital due to their accuracy, durability and extra features. In a digital multimeter the signal under test is converted to a voltage and an amplifier with electronically controlled gain preconditions the signal. A digital multimeter displays the quantity measured as a number, which eliminates parallax errors.
