Amp Meter vs. CT Meter
The Amp Meter is a general purpose current meter designed to measure AC & DC currents directly.
The CT Meter is designed to measure AC currents using an external CT and offers improved accuracy over the Amp meter.
| Amp Meter | CT Meter | |
| Measures | AC & DC currents directly up to 5A on circuits carrying less than 42V AC/DC | AC currents with external CT |
| Use with CT? | Yes (up to 10,000A), but not recommended | Yes |
| Use with current shunt? | No - use the Shunt meter | No - use the Shunt meter |
| Accuracy | 1% | 0.5% |
