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|
