Description
M-290RMS AC/DC Mini Digital Clamp Tester (CE)
The M-290RMS AC/DC Mini Digital Clamp Tester (CE) is a compact digital clamp meter designed to measure AC and DC current up to 400A, AC and DC voltage up to 600V, and resistance up to 1000Ω. It features True RMS measurement for AC current and voltage, along with a 30mm clamp opening for current measurement.
The M-290RMS offers 0.01A resolution on its 40A current ranges and includes automatic DC current zero-offset adjustment, Data Hold, and automatic power-off after approximately 10 minutes. Its compact 45 × 180 × 24mm housing and approximately 135g weight make it suitable for handheld measurements.
The tester complies with IEC 61010-1 and IEC 61010-2-032 safety standards, with ratings of CAT II 600V or CAT III 300V. It features a 3999-count LCD display and operates using three AAA batteries.
