Installation and Wiring

This voltmeter ammeter is designed for simple integration. It includes pre-attached wires for quick hookup. Note that the display requires a separate DC supply (4-30V) to power the meter. Typical wiring steps:

• Connect the meter power input to a suitable DC supply (4-30V).
• Connect the voltage sensing leads across the voltage source or output you want to measure (0-100V DC).
• Place the current-sensing lead in series with the load to measure current up to 10A.
• Double-check polarity and secure connections before powering your circuit.

Installation Tips

• Use proper gauge wiring for currents approaching 10A to avoid voltage drop or overheating.
• Avoid measuring currents above 10A to prevent damage to the module.
• If accuracy is critical, allow the meter to warm up briefly after powering it for stable readings.
• Mount the module in a ventilated area if used near the upper temperature rating.

Why Choose This Mini Digital Voltmeter Ammeter

This module is an excellent choice when you need compact, reliable and accurate DC voltage and current monitoring. Its bright dual-color LED, ±1% accuracy and easy wiring make it a practical addition to battery systems, power supplies and DIY electronics projects where space is limited but measurement quality matters.
