Feature:1. High performance, it also has the high reliability, high safety, automatic measuring range, the handheld clamp meter and so on characteristic .2. Has a large screen digital, full range overload protection, data hold, undervoltage indication, automatic shutdown function.3. True RMS measurement can accurately measure frequency voltage, non sinusoidal voltage, and the surge current can measure the surge current RMS.4. Suitable for variable frequency power supply, air conditioning and refrigerator and others refrigeration equipment, and motor performance testing, etc.5. DC current range function is widely used in electroplating, dc welding machine, auto detection and all kinds of DC current measurement occasion which over 500mA.Specification:Condition: 100% NewItem Type: Clamp MeterMaterial: ABSColor: As shown in the pictureBasic functionRangeResolutionAccuracyDC Voltage400mV0.1mV(0.8%+2d)4V1mV40V10mV400V100mV1000V1V(1%+3d)AC Voltage400mV0.1mV(1.2%+5d)4V1mV40V10mV400V100mV700V1V(1.5%+5d)DC Current40A10mA(2%+10d)400A100mA(2%+5d)1000A1AAC Current40A10mA(2%+10d)400A100mA(2%+5d)600A1AResistance 4000.1(1%+5d)4K140K10400K1004M1K40M10K(1.5%+5d)Capacitance10nF0.001nF(3%+5d)100nF0.01nF1uF0.1nF10uF1nF100uF10nF1000uF100nF10mF1uF(5%+5d)Frequency10HZ0.001HZ(0.5%+3d)100HZ0.01HZ1KHZ0.1HZ10KHZ1HZ100KHZ10HZ1MHZ100HZ10MHZ1KHZDuty cycle1%~99%0.001(0.5%+3d)Temperature-50-3001(1%+4d)301-10001(1.9%+5d)-58-600F1F(1.2%+6)601-1832F1F(1.9%+6)Input impedanceAbout 10MAuto rangeSupportManual rangeSupportTrue RMSSupportInput protectionSupportAuto power-offAbout 10 minutesDiode testIt can measure the LED working voltage below 3VDuty cycle measurementSupportVoltage frequency measurementSupportNCV (charged) measurementSupportOn-off (buzzer gear)SupportLow voltage indicatorSupportData holdSupportJaw size52mm/2.05inSurge signal measurementSupportPower supply1x6F22 9V dry battery (not included).Package List:1 x Clamp Meter(Battery Not Included)2 x Test Leads1 x Thermocouple1 x Cloth Bag1 x Instruction ManualNote:1.
