Feature:1. 3 in 1 Electrician's Tool: a mini pen type tool is a multimeter and IR thermometer and test pen, which integrating three functions into one, thus it is very great for home, office, laboratory, factory, and other application.2. Multimeter Function: including 60V DC/AC voltage measuring, NCV voltage detection, resistance, frequency, continuity, live wire detection, etc. The upgraded voltage sensing probe provide ultra high sensitivity detection.3. Infrared Thermometer Function: -20~380C℃ / -4~716℉ infrared temperature testing range, very simple and and safe to take the temperature with this digital pen type thermometer.4. Live/Neutral Wire Check: safe and easy to distinguish the live / neutral wire by comparing the strength of the detected voltage, the wire that detect the stronger voltage is live wire.5. VFC Test: VFC function can measure the output voltage of inverters.Specification:Specifications:DC Voltage: 0~600V(DC mode), 0.8~600V(Auto mode)AC Voltage: 0~600V(DC mode), 0.8~600V(Auto mode), 10V~600V(VFC mode)Resistance: 0~4000Ω, 4000Ω~40MΩFrequency: 0Hz~200kHz(0~30VAC), 0Hz~1000Hz(0~600VAC)Continuity: YesNon-contactVoltage Induction: YesLive Wire Check: YesAuto-off: About 15 minutesInfraredTemperature: -20~380℃ (-4~716℉)Emissivity: 0.95Response Time: 1sObject Distance Ratio: 4 : 1Material: ABSRange: Automatic rangeAuto Mode: Automatic identification of AC voltage, DC voltage, resistance, continuityDisplay: LCDDisplay Digits: 4000 digitsPolarity Indication: Self-indicating, "-" means Negative polarityOver-range Display: OL or -OLSampling Time: The meter figures show about 0.4 secondsAutomatic Power off Time: 15 minutesBatteryLow Voltage Indication: YesOperating Temperature and Humidity: 0~40℃, 0~80%RHStorage Temperature and Humidity: -10~60℃, 0~70%RHOperating Altitude: ≤2000mPower Supply: 2 * 1.5V AAA battery(NOT included)Item Size: 190 * 31 * 30mm / 7.48 * 1.22 * 1.18in Item Weight: 86g / 3.03oz.Package List:1 x Host1 x English Manual1 x Meter Pen1 x Tool Bag1 x Screwdriver
