• (1) LF Audio High Precision Voltmeter (2-Point Monitoring)

Meet the HPVM (High Precision Voltmeter) - the most precise, fastest sampling, smart wireless graphing voltmeter designed for both automotive and car audio enthusiasts.

Voltage, whether you're using it to create a spark to create combustion, inverting it to drive an electric motor, or pushing it into your amplifier to move a speaker cone to create sound, is critical in your car. Low voltage creates heat, stresses components, limits output, can affect sound quality, and even leave you stranded (if you don't have enough of it). Make sure your voltage is always on point with the best tool for the job!

The HPVM is a high-precision wireless graphing voltmeter with 99.99% accuracy / up to 3 decimal places of precision (e.g., 15.234v), and can monitor up to 2 individual voltage points! See the voltage sag between your alternator, front battery, lithium bank, and/or your amp to ensure your electrical resistance is dialed in and on point!

It is physically overbuilt with a solid aluminum case, high-density/temperature internal supports, and gold-plated ENIG PCB to survive the loudest and most violent builds.

Onboard AuralSync™ technology lets you connect the voltmeter to your smartphone, our AuralSync Companion Smartwatch, and other LF Audio AuralSync™ enabled devices.

The devices features 10 different customizable gauge faces, customizable voltage ranges, optional min/max voltage hold, and even a deep sleep mode!

In deep sleep mode, the device enters, w hen the meter detects that your car has gone to sleep (voltage is slowly dropping, no transients, etc...) it will enter a very low power mode.

During normal operation, the meter consumes roughly 460mW of power. During deep sleep mode, the meter only consumes 167mW of power.

This means that on a normal 100ah 12v agm battery, the unit would drain the battery in 7059 hours, or 294 days.

Once the unit detects a spike in voltage, it will return to normal full-speed operation. The unit will display how much battery drain occurred while it was in low power mode and will also show a bright red warning if the voltage drop was substantial indicating an unhealthy battery or abnormal vampire load.
