Hks-va028-v2.0
Since HKS-VA028-V2.0 is not a publicly listed consumer-friendly part number on HKS’s global or Japanese primary catalogs (as of 2025), it is strongly advised that you:
Note: If this identifier appears on a software file (e.g., .bin, .hex, or .pdf), treat it as a proprietary revision; do not attempt to flash or install it without explicit matching hardware and HKS guidance.
The HKS-VA028-v2.0 is a specific model of a Mini Digital Voltmeter Ammeter commonly used for precision electrical monitoring in automotive, solar, and DIY electronic projects. It is a "Panel Amp" meter that provides real-time dual displays for voltage and current. 1. Technical Specifications While specific datasheets can vary by manufacturer, the HKS-VA028-v2.0
generally follows these standard specifications for the 0.28" digital tube series:
Measuring Range: Typically DC 0V–100V for voltage and 0A–10A for current.
Operating Voltage: The meter itself requires a power supply between DC 4V and 30V. Accuracy: Standard measurement accuracy is approximately hks-va028-v2.0
Resolution: Voltage resolution is 0.1V, and current resolution is 0.01A.
Display: Dual 0.28-inch LED digital tubes, often in contrasting colors (e.g., Red for Voltage and Blue for Current). Dimensions: Approximately 2. Wiring and Installation
Proper installation is critical, as incorrect current lead placement can damage the unit. According to technical guides for the VA028 series, the standard wiring is as follows: Voltage Leads (Thin Wires): Red: Positive power supply for the meter (4V–30V). Black: Negative/Ground for the meter.
Yellow/White: The "sensing" wire that connects to the positive terminal of the load being measured (0V–100V). Current Leads (Thick Wires): Red: Connects to the negative terminal of the load.
Black: Connects to the negative terminal of the power source. Since HKS-VA028-V2
Note: The ammeter must be connected in series on the ground/negative side of the circuit. 3. Common Applications
Automotive Performance: Monitoring battery health, alternator output, and parasitic drains in high-performance or off-road vehicles.
Fuel Injection Systems: Used in some specialized tuning setups where current reading accuracy impacts fuel injection timing.
Solar Power Systems: Monitoring the charging current and battery voltage in small-scale off-grid setups.
