It can be widely used in electrical testing, automotive repairing, industrial electrical maintenance, etc. Features: Concise Appearance: Large screen multimeter with ergonomic body, compact and portable, comfortable operation, easy to carry, save backpack space. High Accuracy: Intelligent micro-controller chip, high precise, power on direct measurement, and with data retention function. One button to open intelligent identification, no need to shift, extremely fast measurement, say goodbye to the tedious. Digital LCD Display: Digital LCD display with red and green backlight, large screen display readings at a glance. Applicable to various measurements under complex environments, greatly enhances the reading experience. Multiple Measurement Functions: Auto-ranging, supports DCVoltage, ACVoltage, VFC (Variable Frequency Voltage), resistance, continuity, diode, capacitance, frequency, duty cycle, true RMS, and temperature measurement; with AUTO mode, NCV sensing (V-Alert), and firewire discrimination function. Low-sensitivity and high-sensitivity two voltage sensing modes are adjustable. No signal input for about 15 minutes, the meter automatically shuts down. VFC Inverter Test: The VFC function measures the voltage of the output inverter and motor. Breakpoint Judgment: Automatic breakpoint detection function, using the NCV function to sense the voltage, along the energized wire to find a normal place to alarm, breakpoint sensing becomes weak or no response. Zeroline & Fireline Detection: In LIVE wire detection mode, a single pen can be used to detect the fireline; if the fireline is detected, the backlight turns red and promotes an alarm sound; if the zeroline is tested, there is no response. Buzzer Alarm:: Sound and light dual alarm design, with loud sound prompts and with screen with a red backlight. Built-in Lithium Battery: Built-in 3.7V, 400mAh lithium battery, with Type-C interface for direct charging the lithium battery, with long endurance. Wide Applications: It can be widely used in electrical testing, automotive repairing, and more household improvements, industrial electrical maintenance, etc. Specifications: Name: Multimeter Material: plastics Battery: 1 * built-in 400mAh lithium battery (included) Display: 6000 counts Display: LCD display with backlight DCVoltage: 0-620V ACVoltage: 0-620V AC/DCCurrent: 1.0-610.0mA Resistance: 0-60.00m, 1 Capacitance: 1.00nF-60.00mF Frequency: 1.000Hz-9.999MHz ON/OFF buzzer: Yes Live Wire Check: Yes NCV test: Yes Item size: 181.5 * 32.6 * 25mm / 7.15 * 1.28 * 0.98in Item weight: 86g / 3.03ounce Package size: 200 * 82.5 * 42mm / 7.87 * 3.25 * 1.65in Package weight: 251g / 8.85ounce Packing List: 1 * Multimeter 1 * Pair of Test Pen 1 * Cable 1 * User Manual 1 * Carrying Bag
