Auto-Connect L1VMR Voltmeter Red

The Auto-Connect L1VMR is a digital voltage indicator that provides a direct real-time transmission of the system voltage. Voltage monitoring helps to detect charging problems, low batteries or voltage drops that affect audio performance. The device provides stable readings over a wide operating voltage range of 9 to 16 volts.

- Precise digital 9-16V volt monitor
- 3-wire connection (+12V, ground, remote connection)
- Adjustment/calibration screw
- Substructure housing
- Red LED backlight

Digital voltmeter:
Monitoring the on-board voltage is essential in car electronics and audio applications. Voltage drops can lead to reduced and distorted amplifier output, unstable operation, unexpected shutdowns or even a faulty amplifier. This voltmeter provides a clear numerical display, allowing you to quickly check the battery condition and charging behavior during operation or when starting.

Thanks to its compact housing and flush mounting, the L1VMR can be installed directly into dashboards, panels or individual trim parts. This means that the display remains easy to read and the factory-style look is retained. The front panel can be easily removed and fixed in the desired position using the screw holes behind it. Alternatively, a strong double-sided adhesive tape can also be used.

To adjust and calibrate the displayed voltage, use the adjustment screw behind the front panel. For accurate measurement of voltage drops, we recommend connecting the voltmeter directly to the same power source as your amplifier.
