How accurate are clamp-on amp meters?
Current measurements are accurate to within 5%, and voltage within 3% of the measured variable. Like most inexpensive meters, this makes it suitable for troubleshooting but not configuration.
What should I look for in a clamp meter?
To help choose the right product in your category of clamp meter, here is the essential check list:
- Minimum and maximum current levels.
- Safety Installation Category Rating for your application.
- Resolution and accuracy to accurately measure the minimum level of current.
- Jaw size for access and maximum conductor size.
Can a clamp meter measure DC amps?
Hall Effect clamp meters can measure both ac and dc current up to the kilohertz (1000 Hz) range. Like current transformer types, Hall Effect clamp meters use rigid iron jaws to concentrate the magnetic field that encircles the conductor being measured.
Are clamp meters better?
If you simply want to measure current, a clamp meter is ideal, but for other measurements such as voltage, resistance, and frequency a multimeter is preferred for better resolution and accuracy. If you are all about safety, clamp meter might be the best tool for you as it is safer than a multimeter.
