Amp Meter vs. Shunt Meter
The Amp Meter is a general purpose current meter designed to measure AC & DC currents directly.
The Shunt Meter is designed to measure DC currents using an external Shunt and offers improved accuracy over the Amp meter.
| Amp Meter | Shunt Meter | |
| Measures | AC & DC currents directly up to 5A on circuits carrying less than 42V AC/DC | DC currents with external Shunt |
| Use with Shunt? | No | Yes |
| Use with current transformer | No - use the CT meter | No - use the CT meter |
| Accuracy | 1% | 0.5% |
