The 4 in 1 DC Solar Voltmeter Ammeter Power Shunt HD Color Screen D69-3061 is a multifunction digital measuring device designed for accurate monitoring of DC electrical systems. This advanced meter can measure voltage, current, power, and energy in one compact unit, making it ideal for solar power systems and DC applications. Equipped with a high-definition color display , the D69-3061 offers clear and easy-to-read measurements even in low-light conditions. It uses an external power shunt to provide precise current readings, ensuring reliable performance for professional and DIY use. This meter is commonly used in solar panels, battery systems, DC power supplies, inverters, and electric vehicles . Its compact design allows easy panel mounting, while its durable build ensures long-term operation. Features: The full-view color LED display displays four electrical parameters : DC voltage, current, power, and electricity. The automatic saving function of power measurement data: when power is off, the meter will automatically save the current power value and automatically read the deal after the next power-on, and continue accumulating the accumulated value. Press and hold the reset button on the front panel of the meter for 5 seconds, and the accumulated power value of the meter will be reset to zero. This meter does not need an external working power supply and the measured voltage is the working voltage of the meter. Specifications: 1. Full-view HD LCD screen 2. Display DC voltage, current, active power, electric energy 3. Energy will be saved when power off 4. Long press the RESET button for 5 seconds, and the energy will be cleared. Product name: LCD numerical DC meter Display: HD LCD color display Dimensions: 79 x 43 x 48mm Installation size: 76 x 39mm Measurement accuracy: 1%±2 words Function test: DC voltage, current, power, electric energy (electricity) 1. Working voltage:14-600VDC 2. Measuring voltage: DC14-600VDC 0-0-100.0A 3. Measuring power: 0-60000W 4. Measurement accuracy: 1% level Attention 1. The meter should use in the indoor, do not use the outside door. 2. When measuring voltage or current exceeds the rating, the meter will be destroyed. 3. You should connect the wire As the wiring diagram indicates, the meter will destroy with the wrong wire connecting. 4. DC current shunt must connect follow the wiring diagram to the negative of the “measuring/working voltage”, the the meter will destroy with a wrong wire connecting. 5. The negative of “measuring/working voltage” should not connect to the terminal of 3, you must first connect to the DC current shunt, then connect to the terminal of 3 (You must follow the wiring diagram) 6. If you only measure the voltage, the DC current shunt and the payload is not necessary, you can only connect the positive of “measuring/working voltage” to the terminal of 4 and the negative to the terminal of 3. Uses: Solar power systems Battery monitoring DC power supplies Inverters and UPS systems DIY and industrial DC projects Package Includes: 1 × DC voltmeter 1 x Shunt 100A
