The HKS-VA028-V2.0 is a compact, digital dual-display DC voltmeter and ammeter used primarily for monitoring automotive electrical systems or DIY electronics. It typically features a 0.28-inch LED display that shows voltage (often in red) and current (often in blue) simultaneously. Key Specifications Voltage Measurement Range: DC 0–100V.

Current Measurement Range: DC 0–10A (most common version includes a built-in shunt).

Operating Voltage: DC 4–30V (Note: Exceeding 30V on the power input will damage the unit). Accuracy: Typically ±1%. Dimensions: Approximately 48mm x 29mm x 26mm. Wiring Guide The device usually comes with two wire harnesses: Thin Wire Harness (Power & Sensing): Red: Power supply positive (4–30V). Black: Power supply negative/ground.

Yellow/Blue (thin): Voltage measurement wire (connect to the positive of the source you want to measure). Thick Wire Harness (Current Measurement): Thick Red/Blue: Connect to the negative side of the load.

Thick Black: Connect to the negative side of the power source (ground). Important Safety Tips

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

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. The HKS interface is menu-driven

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.

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.

HKS-VA028-V2.0 is a specific hardware revision for a digital DC voltmeter and ammeter

module. This compact panel meter is widely used by electronics hobbyists and engineers to monitor real-time voltage and current in power supplies, battery chargers, and DIY solar setups. Overview of the HKS-VA028-V2.0 The "0.28" in the model name refers to the 0.28-inch LED display Appendix B: Revision History

. These modules are popular because they integrate two essential measurements into a single, space-saving unit. The V2.0 revision often includes minor improvements in power efficiency or measurement stability over previous versions. Core Specifications

While specific tolerances can vary by manufacturer, standard specs for this module include: Voltage Range: 0–100V DC (though some variants support up to 500V). Current Range: Standard models handle up to Display Style: Dual 3-digit LED (usually for voltage and for current). Power Supply: Requires its own operating voltage (usually DC 4–30V ) to power the LEDs. Generally around , which is sufficient for most hobbyist projects. Key Features Built-in Shunt:

For the 10A version, the current-sensing shunt is typically built directly into the PCB, meaning you don't need a bulky external component. Calibration Potentiometers:

Most V2.0 boards feature two small trim pots on the back, allowing you to fine-tune the voltage and current readings against a professional multimeter. Simple Wiring:

It usually comes with two sets of wires—a thin set for power and a thick set for measuring the load current. Common Use Cases Bench Power Supplies:

Adding a digital readout to a custom-built or older analog power supply. Battery Monitoring:

Keeping an eye on the discharge rate and voltage levels of Li-Po or Lead-Acid batteries in RVs or e-bikes. Solar Systems:

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
