Monitor your DC power systems with precision using this dual-display digital voltmeter and ammeter. It provides real-time readings for voltage from 0.0V to 100V and current across three selectable ranges (10A, 50A, 100A) on a bright 0.56-inch LED screen. This 2-in-1 meter is a reliable tool for keeping an eye on the electrical health of your electromobile, motorcycle, car, or DIY electronics projects.
This voltage and current tester combines two essential measurements into one compact panel. The red and blue LED display allows you to quickly glance at both voltage and current simultaneously, making it easy to detect fluctuations or diagnose issues in your circuit. With a measurement accuracy of 1% and a fine resolution of 0.01A for current and 0.1V for voltage, you get dependable data for troubleshooting or performance monitoring.
Built for practical use, this panel meter operates within a wide voltage range of 4.5-30V DC and functions reliably in temperatures from -10 to 65 degrees Celsius. Its small footprint (48.00x29.00x21.00mm / 1.89x1.14x0.83inch) allows for easy integration into tight spaces like a car dashboard, battery charger, or power supply unit. The durable construction ensures it can handle the demands of regular use in automotive, industrial, or home workshop environments.
Setting up this DC voltmeter ammeter is straightforward for those with basic electrical knowledge. It is an essential tool for anyone who needs to verify power output, check battery health, or ensure their devices are operating within safe electrical limits. Whether you are working on a car audio system or a solar power setup, this meter provides the clarity and accuracy you need.

Usage Scenario
Mark was troubleshooting a parasitic drain on his car battery that was leaving it dead every morning. He connected this digital voltmeter ammeter in line with the battery's negative terminal. The red and blue display immediately showed a current draw of 0.35A even with the car off. By watching the ammeter reading, he was able to pull fuses one by one until the current dropped to near zero, quickly identifying the faulty aftermarket radio that was the culprit. The clear voltage reading also confirmed his alternator was charging correctly at 14.2V.
Micro Comparison
While basic analog testers can give you a rough idea of voltage, they lack the precision and current monitoring capability of this digital panel. Unlike single-function meters that require you to switch modes, this 2-in-1 display shows you both voltage and current at the same time, saving you time and effort during diagnostics. Its compact LED display is easier to read in dim conditions compared to standard LCD screens, making it a more practical choice for automotive and workshop use.

Questions and Answers
Question: Can this meter measure AC voltage and current?
Answer: No, this meter is designed specifically for DC (Direct Current) systems only, with a voltage range of 0.0V to 100V.
Question: What does the red and blue display show?
Answer: The red LED display typically shows the voltage reading, while the blue LED display shows the current (amperage) reading.
Question: Do I need a shunt for the 50A or 100A version?
Answer: Yes, a meter with a range of 50A or 100A must be connected to an external shunt to measure current, regardless of whether the measured current is less than 10A.
Question: What is the maximum input voltage for the meter's power supply?
Answer: The working voltage for the meter itself is 4.5-30V DC. Do not exceed 30V input to the meter's power terminals to avoid damage.
Question: Is this meter suitable for monitoring a car battery?
Answer: Yes, it is ideal for monitoring 12V and 24V DC systems like car, motorcycle, and electromobile batteries, as long as the voltage stays within the 0-100V range.
