Affordable Wiring & Compact Design: When testing voltage and current, the DROK tester multimeter with three wiring terminals requires no additional power supply as power comes from the circuit. Furthermore, this meter can display voltage and current simultaneously in such a small size (70mm * 40mm * 30mm).
Wide Measurement Range: The multimeter has a wide measurement range (voltage measurement range: DC 4.5-100V; current measurement range: 0-50A. Note: It is best to test above 20A to minimize errors). Additionally, this meter has separate potentiometers for voltage and current calibration. If there are errors, you can adjust them yourself.
Common Ground Design: The DROK volt-ampere meter digital has three wiring terminals; when testing voltage and current, power comes from the circuit, so no other power supply is needed.
Strong Anti-Interference Capability: The current voltage monitor has strong anti-interference capability, allowing it to display a fast refresh rate. With exquisite SMT technology, it has good consistency. This ammeter/voltmeter panel has a shell, making it safe, reliable, and dustproof.
Wide Application: The DROK DC voltmeter/ammeter has a convenient design and wide range of applications; for example, it can be used to monitor changes in the voltage and current state of batteries, DC adjustable power supplies, or other devices.
