The SMD VM-1 Voltmeter is a high-quality device designed to measure voltage in 12V systems. It is suitable for use in a variety of applications, including automobiles, motorcycles, golf carts, ATVs, and side-by-sides. The voltmeter utilizes analog circuitry in conjunction with a digital-to-analog converter to provide accurate voltage readings. A key feature of its design is its internal calibration, which ensures that the device remains accurately calibrated even when subjected to vibration.

Technical Specifications:

Display Range: 10.1 - 15.8 Volts DC
Accuracy: +/- 0.15 Volts
Response Time: 130 milliseconds (for readings between 10.1 - 15.8 Volts)

Installation:

The installation process for the VM-1 Voltmeter is straightforward and involves a few key steps:

Disassembly: Begin by unsnapping the four tabs that secure the display to the mounting plate. This is done by pressing the tabs toward the display while simultaneously lifting the display away from the mounting plate.
Mounting Plate Preparation: Use the mounting plate as a template. Place the flat surface of the mounting plate against the desired flat mounting surface on your vehicle. Mark the locations for the two screw holes and the rectangular slot for the wiring.
Drilling: Drill the two screw holes using a 3/32" drill bit. Drill the hole for the wires using a 3/16" drill bit.
Mounting the Plate: The mounting plate must be mounted on a flat surface. Failure to do so can cause distortion of the plate, which will prevent the face from snapping on properly. If a flat surface is not available, the plate can be mounted using a high-quality automotive-grade tape, such as VHB tape by 3M™.
Connecting the Display: Bring the display toward the mounted plate. Pass the wires through the 3/16" hole that was drilled for wiring. Once the wires are through, snap the display onto the mounting plate.

Electrical Connections:

The VM-1 Voltmeter requires three electrical connections:

Voltage Sense Wire: RED
Turn On Trigger: White
Ground: BLACK
