Overview: The AC Clamp Meter models CM3281 and CM3291 are designed for measuring large currents with ease, featuring a large jaw diameter of 46 mm. They are durable, capable of withstanding a 1-meter drop onto concrete, and are suitable for measuring thick cables directly at the terminal.
Specifications:- Jaw Diameter: 46 mm (1.81 in)
- AC Current Measurement: 42.00 A/420.0 A/2000 A with an accuracy of ±1.5% rdg.±5 dgt.
- AC Voltage Measurement: 4.200 V to 600 V across 4 ranges with an accuracy of ±1.8% rdg.±7 dgt.
- DC Voltage Measurement: 420.0 mV to 600 V across 5 ranges with an accuracy of ±1.0% rdg.±3 dgt.
- Resistance Measurement: 420.0 Ω to 42.00 MΩ across 6 ranges with an accuracy of ±2.0% rdg.±4 dgt.
- Operating Temperature: -25°C to 65°C (-13°F to 149°F)
- Drop-proof: 1 m onto concrete
- Power Supply: Coin type lithium battery CR2032
- Dimensions: 57 mm W × 198 mm H × 16 mm D, 103 g
Features:- CM3281 uses MEAN Value method, while CM3291 uses True RMS method.
- Data hold and auto power-saving functions are included.
- Comes with a carrying case, test lead, battery, instruction manual, and operating precautions.
Optional Accessories:- L9208 Test Lead with anti-short cap
- CT6280 AC Flexible Current Sensor for measuring large currents in small spaces
- L4933 Contact Pin Set and L4934 Small Alligator Clip Set for enhanced connectivity
Standards and Compliance: The devices comply with safety standard EN 61010 and EMC standard EN 61326.
Comparison: The CM3281 and CM3291 models differ primarily in their measurement methods (MEAN vs. True RMS) and frequency characteristics, with the CM3291 offering a broader frequency range (40 Hz to 1 kHz).
