Extech Clamp Meters Editorial Review
The Extech MA445 is a True RMS 400A AC/DC Clamp Meter with NCV. It has a range of features including the ability to measure temperature in both degrees Fahrenheit and degrees Celsius, millivolts, and both AC and DC current up to 200A. The meter is compact and versatile, and its measurement modes are easy to set. However, there are some drawbacks to consider. The low DC current readings have been reported as inaccurate and inconsistent by some users. The display is difficult to read and does not have a backlight. It is also frustrating to have to press a button to switch between AC and DC modes. Overall, the Extech MA445 is a decent clamp meter with some useful features, but there are some areas for improvement.
