Accurately Measures: AC/DC voltage, AC current, resistance, frequency, Capacitance, Temperature, diode, continuity buzzer and induced voltage tests. The Clamp measures the AC current in a conductor up to 25mm without interrupting the circuit. Additional Features: Data hold, max reading, and an easy-to-read large LCD. Automatically enters sleep mode after 15 minutes of inactivity for energy conservation.Stable performances, high reliability, clear reading and overload protection. NOTE: This meter cannot test DC Current; Ensure your multimeter is set to the correct setting before testing Specifications: DCV: 400mV~600V ±1.8% ACV: 4V~600V ±2.0% ACA: 4A~400A ±2.8% Resistance: 400Ω~40MΩ ±2.0% Frequency:10Hz~4MHz ±2.5% Capacitance:4nF~4mF ±8.0% Temperature: 0°C(32℉)~750°C(1382℉) ±2.6% LCD Size: 34x28mm Max Display: 4000 Low Battery Indication: yes Diode Test: yes Continuity Buzzer test: yes Induced Voltage Test:yes Automatic Shutdown:yes Auto Range: yes Overload Protection: yes Jaw Opening Size: 30.7mm Power Supply: 2x1.5V AAA battery (included) Product Size: 187×66×32mm Product Weight: about 130g Package Includes: 1 x Digital Clamp Meter 1 x Test leads 1 x User Manual
