: Built for easy integration into control panels or project boxes with a snap-in mounting system. Durability
Connect the thin yellow wire to the positive rail of the target high-voltage system.
The HKS-VA028-V2.0 uses a standard 5-wire split harness configuration divided into a thin-wire logic connector and a thick-wire current tracking connector. Correct wire orientation is vital; reversing the polarity on the measurement or supply lines can permanently fry the onboard microprocessor. The 3-Wire Thin Harness (Logic & Voltage Sensing)
Most 10A versions of the HKS-VA028-V2.0 feature an onboard shunt, allowing for direct wiring without external components. hks-va028-v2.0

Connects directly to the positive terminal of the target source to sample live voltage. System Integration Layouts
Connect a reliable, calibrated handheld digital multimeter (DMM) in parallel with the load to check voltage. Turn the screw with a precision screwdriver until the LED matches the DMM readout. : Built for easy integration into control panels
By providing concurrent tracking of electrical parameters up to , the V2.0 iteration refines the signal processing and physical calibration layout over its predecessor. Core Specifications & Operational Boundaries
The HKS-VA028-V2.0 Go to product viewer dialog for this item.
For measurements falling below 10V, the digital logic automatically shifts the decimal point to present two fractional positions ( Correct wire orientation is vital; reversing the polarity
The device usually features a configuration divided into two harnesses:
The HKS-VA028-V2.0 is a 0.28-inch LED digital panel meter that combines a DC voltmeter and an ammeter into one unit. It is often referred to in the market simply as a "10A/100V Dual Digital Meter." The "V2.0" designation usually implies an updated design for better stability or screen brightness.
