: While generally reliable for general monitoring, users have noted that accuracy can vary between units. Some testers found the voltage readings to be within 1%, but current readings occasionally required calibration using the built-in trimmer potentiometer.
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
HKS-VA028-V2.0: A Complete Guide to the Compact Digital DC Voltmeter/Ammeter
The VA028-V2.0 uses a sophisticated algorithm to analyze the vehicle's driving conditions and adjust its performance accordingly. This allows drivers to enjoy optimized performance, regardless of their driving style or conditions. hks-va028-v2.0
Provides a low-cost visual upgrade for DIY or legacy analog variable power setups.
The V2.0 ships with a 0.8 bar spring. For low-boost applications (<1.0 bar), install no shims. For 1.2–1.5 bar, add the included 0.3mm shim. For racing (>1.8 bar), purchase the HKS VA028-SPRING-HD kit.
The logic supply voltage (thin red wire) is dropping below 4.5V. Switch to an isolated power supply rather than tapping the monitored circuit. : While generally reliable for general monitoring, users
: Unlike analog gauges, it has no moving parts (springs or needles), making it resistant to vibration and fatigue in harsh environments like high-performance vehicles. Common Applications Solar Power Systems
Note: The ammeter must be connected on the ground/negative side of the circuit. 3. Common Applications
