| Analog voltmeter |
Digital voltmeter |
| In analog voltmeter the output signal representation is done by using potentiometric deflection. |
In digital voltmeter the output signal is represented in the digital form. |
The different type are:
- Average reading
- True rms reading
- Sampling type etc.
|
The different type are:
- Ramp type
- Integrated type
