High Precision Voltmeter - Pro

HPVM Pro Voltage Meter Precision volt meter for automotive and car audio 2-inch LCD with 65,000 colors Monitors four sources simultaneously Measures up to 18 volts A gauge face for every style, with sharp numbers and smooth dials Competition face holds the lowest voltage of each hit Bluetooth-enabled connection with free AuralSync app Your Style. Our Precision. Able to monitor four sources at once, the HPVM Pro is the most versatile graphing voltmeter available today, accurate to 2/1000 of a volt. The HPVM comes equipped with Bluetooth connectivity, allowing it to connect to thefree AuralSync™ app, optional AuralSync™ Companion Smartwatch, and otherAuralSync-enabled devices. Pick your gauge face in the free AuralSync™ app. See each face live, just as it looks on your meter. Then set your own voltage ranges and colors. Want big numbers, a dial or a graph? Take your pick. Tiles and Rings show all four channels at a glance. The Sag face shows how far each channel drops under load. The Wire Loss face shows how much voltage your wiring loses. The Night face uses dim orange numbers for driving after dark. Running a 4S lithium bank? The Pro can show the voltage of each cell. The HPVM also features wiring terminals on the back and bottom of the unit foradditional mounting options, and a clean look. Made for Competition The Competition face shows your live voltage. On every hit, it holds the lowest voltage on screen. It stays up long enough to read. Tune it in the app on your own live voltage. Choose how big a drop counts as a hit. Choose how long the low stays up. Reset it with a tap. Easy Settings in the App Every meter setting sits on three tabs: Face, Voltages and Meter. Set your gauge range, color zones and sleep voltage on one live scale. Calibrate the meter to your own multimeter in a few steps. Built To Last Extremes in vibration, humidity, and temperatures are always attacking everything inyour vehicle. A solid aluminum case houses high-density/temperature internal supports,and gold-plated ENIG PCB to survive, and thrive, in any build. Advanced Power Management The HPVM’s innovative Deep Sleep mode is engineered to minimize powerconsumption, drawing just 167 milliwatts when it senses a gradual voltage drop withouttransients. This ensures minimal battery drain, taking up to 294 days to deplete a fullycharged 100 amp-hour 12V AGM battery. While in low-power mode, the HPVM Pro continuously monitors cumulative batterydrain. A prominent red warning signal is triggered by significant voltage drops, flaggingpotential issues such as excessive parasitic loads or a failing battery. This intelligentdesign ensures early detection of power system issues, identifying issues like a weakbattery or excessive parasitic draw, before they become bigger problems. The system’s rapid response circuitry also ensures immediate reactivation upondetecting a voltage spike, seamlessly resuming full operation, and offering real-timeupdates to keep you informed.
