The Wire Meter

The Wire Meter Wireless Voltage Monitor

Monitor your system voltage in real time without running a single wire.

The Wire Meter is a compact wireless voltmeter designed for car audio setups, battery monitoring, and clean installs. It lets you keep track of your voltage from anywhere in your vehicle with a dedicated display — no apps, no delays, no guesswork.

Built for reliability and simplicity, the system uses a transmitter connected to your power source and a separate display unit that receives the signal instantly.

⚡ How To Use

1. Connect the Transmitter

   - Connect the transmitter to your power source (positive and ground).

   - This is the voltage you will be monitoring.

2. Power the Display

   - Power the display using either:

     - USB-C, or

     - 12V input (internal converter steps it down automatically)

3. Automatic Pairing

   - Units come pre-paired from factory.

   - Once powered, the display will automatically receive voltage data.

4. Read Your Voltage

   - The main number shows real-time voltage.

   - Bottom row displays:

     - Minimum voltage

     - Maximum voltage

5. Signal Indicator

   - Signal bars show connection strength.

   - If signal is lost, the display will hold the last reading briefly before disconnecting.

💡 Notes

- Designed for 12V systems (safe operating range up to ~17V input)

- No app required — fully standalone system

- For best performance, avoid enclosing antenna in heavy metal surfaces
