Providing real-time diagnostics for DC-driven machinery. Important Installation Note
The VA028 is a masterpiece of engineering. It offers a tactile, analog tuning experience that modern laptop tuning lacks. Treat it with respect, wire it cleanly, and it will serve you well.
Monitoring power consumption of motors and electronics. Troubleshooting & Tips hks-va028-v2.0
Prevents the device from burning out if the power supply wires are swapped accidentally.
: Many Japanese Domestic Market (JDM) vehicles, from sports cars to luxury sedans, are electronically limited to a top speed of 180 km/h (about 112 mph). The HKS VAC/SLD is an electronic device that intercepts the speed signal from your car's CAN (Controller Area Network) communication system. By modifying this signal, the VAC allows the ECU to think the car is traveling slower than it is, effectively removing the factory-imposed speed governor and allowing the car to reach its full mechanical potential. This is a critical mod for track driving or high-speed events. Providing real-time diagnostics for DC-driven machinery
(often associated with high-performance automotive parts or specialized industrial sensors).
Note: The ammeter tracks current on the . It must never be wired directly across the positive and negative rails of a power supply, or it will create a direct short circuit. Wiring Diagrams and Applications 1. Shared Power Source Topology (Measurements Under 30V) Treat it with respect, wire it cleanly, and
Understanding the HKS-VA028-V2.0 Digital Voltmeter Ammeter The is a compact, dual-display digital panel meter designed to simultaneously monitor DC voltage and current. It serves as an essential, cost-effective component for hobbyists, electronic engineers, and DIY builders who need real-time power diagnostics integrated directly into their hardware projects. Technical Specifications
Monitoring the output of small-scale solar panels before they reach a charge controller. Wiring Safety Tip When installing the HKS-VA028-V2.0, ensure the thick black wire
Usually caused if the supply voltage drops below the 4.5V minimum threshold required by the logic board.
Unlike cheaper static alternatives, the rear PCB surface of the V2.0 features . Users can manually fine-tune the calibration of both voltage and current scaling using a precision screwdriver to correct sensor drift over time or account for inline resistance losses. Auto-Shifting Decimal Point
