1. The signal generator is small in size, has many functions, easy to operate and easy to carry.2. The key layout is reasonable, all functions have independent corresponding keys, easy to operate.3. Built-in battery, low power consumption, long standby time.Features:1. Digital Multimeter: The digital multimeter supports AC and DC voltage testing, resistance testing, continuity testing, frequency testing, data hold, automatic shutdown, NVC, True RMS, automatic measuring range, Live wire detecting, diode ( HT124B+ only ), capacitance ( HT124B+ only ).2. 2.5-inch LCD Color Screen: 2.5-inch LCD color screen greatly enhance the reading experience. Backlight function make it very easy to read even in bright sunlight or poor light.3. Smart (AUTO) Measurement: This measurement mode is default when power on. In this mode, DC voltage, AC voltage, resistance, continuity can be measured, and the meter can automatically identify the measurement signal.4. Flashlight Function: Flashlight design lets you test efficiently and comfortably anywhere, indoors and outdoors, day and night. 5. Convenient & Easy The digital multimeter lets you test safely and efficiently light and compact, easy to carry.Note:1. Do not measure the voltage higher than 600V, otherwise the meter may be damaged.2. Pay special attention to safety when measuring high voltage to avoid electric shock or personal injury.3. Before use, test the known voltage with the meter to confirm that the meter is in good condition.4. Due to manual measurement, the size may be slightly different. Thank you for your understanding.5. Due to different light conditions and different monitors, item color displayed in photos may be showing slightly different from real object.Specifications:Model: Type 1 ( HT124A+ ) / Type 2 ( HT124B+) -- OptionalHT124A+: without Capacitance Measurement / Diode TestHT124B+: with Capacitance Measurement / Diode T
