Understanding the Gauges
Before diving into the rest of the guide, spend a few minutes getting to know the layout and features of your Lumen Dash. It’ll make the setup process smoother, and you can always jump back to this section if you need a refresher later.

Installing the Software
Follow the steps below to install the software
Visit our official site:
Download the installer and run the setup file.
Connecting the Device
Follow the on-screen prompts to complete installation.
Follow the instructions below to connect the device:
Connect the provided power supply.
D Use only the included 12V power adapter
Read and follow the warnings and cautions on page ii of this manual.
Use only the included 12V power adapter. Substituting an unapproved power source may results in overheating, malfunction, or permanent damage.
Connect the Lumen Dash to your PC.
With the desktop software running on the computer, the gauges will light up and perform a sweep, and the desktop client will indicate that the device is connected. If this is your first time setting up, the gauges will read zero. Continue to the next chapter to begin displaying real-time system data.
Disconnecting the Device
To disconnect the device, first unplug the USB. Wait for the gauges to return to zero and power off, then unplug the power adapter.

Selecting a Gauge
The three gauges displayed in the desktop app directly match the physical gauges on your Lumen Dash. Click any gauge to select it — it will highlight in yellow to show it’s active. The settings located in the lower section. now apply to the currently selected gauge.
Hardware → Sensor Type → Sensor
With a gauge selected, use the three boxes to configure the data source:
Hardware — Choose the component you want to monitor (e.g., CPU, GPU, RAM)
Sensor Type — Select the type of metric (e.g., Temperature, Clock, Load)
Sensor — Choose the specific reading (e.g., Core 1 Clock, CPU Package Temp)
Once selected, the gauge will begin displaying that sensor's data in real time. The hardware type and units are displayed in the box to the left.
Saving and Loading Presets
Once you've configured your gauges, you can save the setup as a preset for quick access later.
To save a new preset:
Configure the gauges how you want them in the preset.
Click the "+" icon next to the preset drop-down.
Enter a name for your preset.
Press Enter to save.
Presets store:
Gauge assignment (left, middle, right)
The chosen hardware, sensor type, and sensor
Any scaling values you've applied
You can switch between presets at any time using:
The drop-down located in the main layout
The system tray menu
Presets are ideal for swapping between different monitoring modes, such as:
A gaming preset with GPU temp, CPU usage, and fan speed
A bench-marking preset with clock speed, voltage, and temperature scaling To delete a preset, open the Settings menu and select the preset from the drop- down.
Adjusting Gauge Scaling
Many sensor values such as temperatures and percentages fall between 0 and 100, but some sensor values — like clock speed or fan RPM — can exceed the gauge’s default range of 0 to 100. You can customize the scale to match the data you're monitoring, which is helpful when monitoring hardware metrics that have a wide range or when focusing on a specific performance window.
For high-range values (e.g., clock speeds up to 10,000 MHz), you might use a scale like 0 to 10,000
To focus on a specific range — say, 100 to 200 — you can enter those values to “zoom in” on that window, making subtle differences more visible on the gauge
To display these properly, you can enable scaling for each gauge:
The scaling toggle is located to the left of the Hardware selection box.
Once enabled, the user is able to adjust the minimum and maximum values for that gauge.
By default, gauges are scaled from 0 to 100.
Lumen Dash automatically maps incoming values to a percentage of your chosen scale, ensuring the needle reflects your custom range. For example:
With a 0–10,000 scale, a value of 5,500 reads 55
With a 100–200 scale, a value of 180 reads 80
This gives you full control over how the gauges respond — whether you want a full-range overview or a zoomed-in look at fine changes in a narrow band.
System Options Menu
The System Options menu allows you to configure global settings that affect how the Lumen Dash behaves across all gauges. These options are accessible via the gear icon in the upper-right corner of the desktop application.
