Feature:1. This pen type digital meter is a small 3 3/4 bit true RMS automatic scanning digital instrument. According to the difference between voltage and resistance, operator do not need to turn the dial to select the function, because of its automatic identification measurement.2. The stable performance, high precision, high reliability, clear reading, overload conservation function are achieved. And this meter charged by AAA 1.5V low battery. and with VA reverse display screen, screen reflection for easy response to various environmental issues, it is cherished by most people.3. Digital multimeter supports NCV non-contact voltage detection, and can distinguish the null line and the fire wire to avoid the risk of electric shock. Safe and reliable.4. This new type of meter also automaticaly identify Dc voltage, Ac voltage, resistance, continuity, without any selection,besides with the function manually switching to measure electric field induction and fireline discrimination. it will be an ideal tool for radio enthusiasts and families, thanks to its superior performance.5. The pen multimeter has an automatic shutdown function, which will automatically shut down if there is no operation for mins, lowe power consumption. Audible + light alarm make measurement more easy.6. Compact pen type design for convenient single hand use, easy to carry and operate. It is very suitable for home, school, laboratory, factory and other applications.Specification:Model: A3005A / A3005B(Optional)Type: Standard Configuration / High Configuration(Optional)Material: ABSItem Size: A3005A: 170.5 * 25.4mm / 6.71 * 1 inchA3005B: 183.5 * 29 * 24mm / 7.22 * 1.14 * 0..94 inchItem Weight:A3005A: 58g / 2.04ozA3005B: 60g / 2.12ozPackageSize: 188 * 60 * 30mm / 7.4 * 2.36 * 1.18 inchPackageWeight:A3005A Standard Configuration: 122g / 4.3ozA3005A High Configuration: 145g / 5.11ozA3005B Standard Configuration: 124g / 4.37ozA3005B High Configuration: 148g / 5.22ozModelA3005AA3005BAC Voltage4V~600V6V~600VDC Voltage400mV~600V600mV~600VResistance400~40M600~60MCapacitance10nF~40mF10nF~60mFHz Frequency10Hz~10MHz10Hz~10MHz% Duty Cycle0.1%~99.9%DiodeAmbient TemperatureBuzzerNCV Voltage DetectionLive Zero Line IdentificationPhase Sequence DetectionLine BreakpointFind Automatic ShutdownLow Battery PromptFlashlight LightingHold Data RetentionScreenVA color reverse display screen.Package List:1 * Pen-shaped Digital Multimeter 1 * Test Leads 2 * Gold-plated Extra-pointed Hands 1 * In-line Clip 1 * U Plug 1 * Copper and Nickel Plating Needle 1 * Copper and Nickel Plating Short Needle 1 * Banana Pointed Needle 1 * Copper-nickel Plated Flat Head Needle 1 * User Manual (English)Note:A3005A does not include phase sequence test function.
