Difference Between Analog and Digital Multi meter:
Analog multi meter
1. Power supply is not required
2. Less suffered from electric noise
3. It provides measurement in analog form with metal pointer.
4. It uses simple display with markings for various ranges as per R, V and I measurements.
5. It does not require ADC converter i.e. analog to digital converter
6. Accuracy of measurement is lower
7. Input resistance vary as per range to be measured.
8. Simple & rugged in construction
9. Bigger in size
10. Economical
Digital multi meter
1. Power supply is required
2. Suffered from electric noise.
3. It provides measurement in digital form using digits as per resolution needed.
4. It uses LCD display.
5. It requires ADC converter and quantity to be displayed is in digital form.
6. Accuracy of measurement is higher
7. Input resistance is constant for all ranges.
8. Complicated & delicate in construction
9. Compact in size
10. Expensive
