Digital Multimeter Manufacturers

Digital multi meter is also known as a digital volt-ohm meter. In such an instrument, the signal under test is converted to a digital voltage and an amplifier with an electronically controlled gain preconditions the signal. Since the digital display directly indicates a quantity as a number, there is no risk of parallax causing an error when viewing a reading. Similarly, better circuitry and electronics have improved meter accuracy. Older analog meters might have basic accuracies of five to ten percent. Modern portable DMMs may have accuracies as good as ±0.025%, and bench-top instruments have accuracies in the single-digit parts per million figures. The inclusion of solid-state electronics, from a control circuit to small embedded computers, has provided a wealth of convenience features in modern digital meters.
