Designed for 12V/24V systems, it includes a built-in shunt for precise current measurement and reverse polarity protection to prevent damage. With a fast refresh rate and low power consumption, this modern panel meter offers reliable, real-time monitoring in a compact form factor. ## Description Specifications: Voltage measurement range: DC 0V-100V Current test range: 0-10A Working voltage: 4.5-30 V DC (Note: if the voltage exceeds 30V, an external independent power supply is required) Voltage error: ±0.1% Current error: ±1% Working current: <20mA Refresh rate: ≥300mS / times Display: 0.28" Two color blue and red Operating temperature: -15℃ to 70℃ Working pressure: 80 to 106 kPa Package Included: 2 × LED Voltmeter Ammeter Review: How to avoid current measurement error - The current measurement shunt is on the ground side. If you do use current measurement, then leave the small black negative wire on the voltage measurement connector floating. At first I mistakenly connected it to ground, and was getting a large current measurement error. When I let it float, the measurement was pretty accurate. The instructions in the pictures on the desertcart page say, "No need to connect". Ideally it would say, "Don't connect if measuring current". Review: Displays current as well as voltage - Displays amps and volts from my small scale solar array. Been working ok for12months so far. ## Features - Voltage measuring range: 0-100 V DC; current measuring range: 0-10A (decimal point moves automatically). - Display mode: Dual-colour digital display 0.28" LED digital tube Display color red+blue. - Built-in Shunt: The 10A voltage and current meter itself has a built-in shunt. - Color distinction: Led Display Voltage and current simultaneously in different colors, red for Voltage, Blue for current(the current is measured in the negative rail). - Connection Protection: With reverse connection protection to avoid burning from reverse connection. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NDN78FD | | Best Sellers Rank | 49,111 in DIY & Tools ( See Top 100 in DIY & Tools ) 88 in Voltage Testers | | Brand | VooGenzek | | Colour | Red and Blue | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 422 Reviews | | Manufacturer | VooGenzek | | Manufacturer Part Number | GZ039T01 | | Maximum Operating Voltage | 100 Volts | | Measurement Type | Ammeter, Multimeter, Voltmeter | | Min.

Thin red and black wire are the meter power. 5V is best, as higher will make the on-board regulator hot. Then the yellow wire measures the voltage maybe up to 99.9V. The Voltage decimal point doesn't move for less than 1V or at all. The current meter is actually a 1V approximately max voltmeter for 50.0 A on display. Thus the shut drops 0.2V at 10A, which is 2W. I expect the shunt, which is a surface mount resistor gets a bit two hot at 10A. Being experienced at electonics I removed the shunt. Then suitable external resistor can be used, A 20 ohm shunt will thus measure 0 to 50 mA, with the decimal point shifting one to the left for less than 1.0 on the display (was 1A, now 1mA), thus 0.99 down to 0.01. I'd not use the built in shunt for more than 2.5A. The adjusters are to calibrate voltage and current. ## Frequently Bought Together - VooGenzek 2 PCS 0.28" LED Voltmeter Ammeter, Red and Blue Detector Voltage Current Meter Panel Amp Volt Gauge, DC 0-100V 10A for 12V / 24V Multimeter Amperage Meter Volt Amp Gauge Panel - Hailege 3pcs XL4015 5A DC to DC CC CV Lithium Battery Step Down Charging Board Led Power Converter Charger Step Down Module --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/397621898-voogenzek-2-pcs-0-28-led-voltmeter-ammeter-red-blue](https://www.desertcart.no/products/397621898-voogenzek-2-pcs-0-28-led-voltmeter-ammeter-red-blue) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
