uses a split into two separate wiring harnesses: a thin-wire connector for the meter's logic power, and a thick-wire connector handling the heavy current measurement pathway. 1. Thin Wire Harness (Power Supply for the Meter)
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
Due to the niche, often undocumented nature of such parts, detailed information can be hard to come by. This article serves as your complete guide—aggregating knowledge from across the web to help you understand what this code likely refers to, how to evaluate its authenticity and compatibility, and how to troubleshoot common issues. hks-va028-v2.0
: It utilizes a dual-color LED system, often featuring a red display for voltage and a blue display for current. This color coding provides immediate visual cues for circuit status.
The most common usage of "hks-va028-v2.0" points to a . "HKS" often points to automotive aftermarket parts, but in this context, it refers to a generic hardware module used across various applications. The "VA028-V2.0" part of the code tells us exactly what it is: uses a split into two separate wiring harnesses:
The HKS-VA028-V2.0 is a 0.28-inch dual-display LED module designed to monitor DC voltage (0–100V) and current (0–10A) in real-time, often utilized for tracking automotive engine management systems. Engineered for high-performance environments, it features a 5-wire design and offers ±1% accuracy for electrical monitoring, withstanding high vibrations.

The small 0.28-inch display is extremely crisp and bright, making it suitable for automotive dashboards, power supplies, or hobbyist enclosures. 3. Automatic Precision Adjustment Users can manually fine-tune the calibration of both
Pass the ground return of the high-voltage system through the thick red and black wire loop. Calibration and Fine-Tuning
If your car has a resistor box for the injectors (common on older Toyotas), the VA028 installation is different. You must wire it after the resistor box to ensure the voltage drop doesn't interfere with the HKS signal processing.
