Digital Multimeter Professional Tester Meter Alternating Current Direct Current Voltage Multimetro True RMS Capacitance Temp Detector Multitester This digital multimeter has concise appearance, large color display with backlight, clear definition with large font for easy data reading. It can measure multiple electronic values, such as capacitance, true RMS, Diode, temperature, frequency, and resistance, to meet your multi-functional needs. Support for manual selection, data hold, NCV and high/low sensitivity toggle, battery power indicator, on/off test, and Live Wire feature. It can be widely used in electrical testing, automotive repairing, and more household improvements, industrial electrical maintenance, etc. Features: Concise Appearance: Compact, lightweight and portable, easy to carry, with a comfortable grip. Color Display: Large color display with backlight, clear definition with large font for easy data reading. Wire Break Point Detection: The built-in intelligent high-precise sensing chip, which is perfect for detecting the wire break points. NCV Measurement: Induction signal measurement, non-contact design, live line signal is strong and alarm, zeroline signal is weak or even non-responsive. AC/DC Voltage Measurement: Non-contact detection, built-in high-sensitivity sensors that ensure operational safety when measuring electricity, and it will display the current frequency at the same time when this multimeter measures the AC voltage. Fire Wire Recognition: When detected as a live wire, the buzzer will sound an alarm and the support on and off buzzer beep. Bright LED Flashlight: There is a flashlight to help you illuminate and use when measuring in a dark environment. Diversity Measurement: it can measure multiple electronic values, such as capacitance, true RMS, Diode, temperature, frequency, and resistance, to meet your multi-functional needs. Multifunctional Design: Support for manual selection, data hold, NCV and high/low sensitivity toggle, battery power indicator, on/off test, and Live Wire feature. Wide Applications: It can be widely used in electrical testing, automotive repairing, and more household improvements, industrial electrical maintenance, etc. 4 Model Options: You can choose between ZL126A, ZL126B, ZL128A, or ZL128B, depending on your requirements, with the following differences: ZL126A: 6000 counts, manual auto, carbon zinc battery (powered by 3 AAA batteries, not included) ZL126B: 6000 counts, manual auto, built-in battery (USB charging, built-in 1000mAh battery, included) ZL128A: 9999 counts, manual auto, temperature probe, DC/AC Current, break point, carbon zinc battery (powered by 3 AAA batteries, not included) ZL128B: 9999 counts, manual auto, temperature probe, DC/AC Current, break point, built-in battery (USB charging, built-in 1000mAh battery, included) Specifications: Name: Multimeter Type: ZL126A, ZL126B, ZL128A, ZL128B (optional) Battery:  ZL126A/ZL128A: 3 * AAA batteries (not included) ZL126B/ZL128B: 1 * built-in 1000mAh battery (included) Temperature Measure:  Room temperature: 0~60℃ Probe temperature: -50~1100℃ Direct Current Voltage: ZL126A: 0.5V-600V (Auto), 0V-600V (Manual) ZL126B: 0.5V-600V (Auto), 0V-600V (Manual) ZL128A: 1V-1000V (Auto), 0V-1000V (Manual) ZL128B: 1V-1000V (Auto), 0V-1000V (Manual) Alternating-Current Voltage: ZL126A: 1V-600V (Auto), 0V-600V (Manual) ZL126B: 1V-600V (Auto), 0V-600V (Manual) ZL128A: 1V-750V (Auto), 0V-750V (Manual) ZL128B: 1V-750V (Auto), 0V-750V (Manual) True RMS:  ZL126A: 40-400HZ ZL126B: 40-400HZ ZL128A: 0-1KHz ZL128B: 0-1KHz AC/DC Current: ZL126A: nonsupport ZL126B: nonsupport ZL128A: 0mA-10A ZL128B: 0mA-10A Frequency: ZL126A: 10HZ-1KHz ZL126B: 10HZ-1KHz ZL128A: 0-10MHz ZL128B: 0-10MHz Ambient temperature: ZL126A: 0℃~60℃ ZL126B: 0℃~60℃ ZL128A: 0℃~60℃ ZL128B: 0℃~60℃ Max count: ZL126A: 6000 counts  ZL126B: 6000 counts ZL128A: 9999 counts ZL128B: 9999 counts Data retention: yes Firewire detection: yes NCV voltage pen detection: yes NCVanalog strip: yes Color display: yes Function indicator: yes Flashlight light: yes Operation mode: Auto Mode + Manual Mode Package size: 150 * 50 * 20mm / 5.91 * 1.97 * 0.79in Package weight: 280g / 9.88ounce Packing List 1 * Multimeter 2 * Universal Test Pen 1 * User Manual
