Why separate the display from the scale?

This design comes from a simple question:

How should a coffee scale better serve the brewing process?

With traditional all-in-one coffee scales, the display is often blocked during brewing by a kettle, dripper, server, espresso portafilter, or cup. Users frequently have to lean forward, tilt their heads, or adjust their posture just to see the data.

WeighMaster features a modular split design that separates the display module from the scale body. This allows you to place the display wherever it is most convenient—next to your dripper, on top of your espresso machine, mounted on a bar stand, or attached to a magnetic surface.As a result, key brewing information such as weight, time, brew ratio, and flow rate remains within your natural line of sight.The goal isn't to make the product modular for the sake of being modular—it's to help you stay focused on brewing, not on finding the display.

Will I need to pay import duties or taxes?

In most cases, our customers do not need to pay additional import fees upon delivery.

However, customs rules vary by country, and any duties, taxes, or customs fees are determined by local customs authorities.

We do our best to make shipping smooth and transparent, but we cannot guarantee the final customs decision in every country.

How far can the display module be placed? Will it still work through a wall?

In typical home or café environments, the connection remains stable when the display module is placed on top of an espresso machine, on a shelf above the brewing station, beside your workspace, or within approximately 5 meters (16 feet) of the scale in an open area.

We do not recommend using the system through walls, around large metal obstructions, or in environments with significant signal interference.

For everyday use in kitchens, coffee bars, cafés, and brewing stations, WeighMaster provides the flexibility to position the display where it is most comfortable and convenient to view.

What is the precision of the scale?

The precision of WeighMaster 2.0 is up to 0.1g.

Can Modules A and B magnetically attach to another magnetic surface?

Yes, the modules have magnets on their bottoms and sides, enabling attachment to the scale body and coffee machine.

How do I turn on my WeighMaster scale and module?

Please note that the scale and module are separate components and need to be powered on individually.

To turn on the WeighMaster scale, locate the power button near the magnetic port on the side of the scale. Slide the switch to the right to turn it on. To turn it off, slide the switch to the middle.

To turn on the WeighMaster module, simply press and hold the power button.

Can I wake the scale and module at the same time?

When the device enters sleep mode, pressing the scale surface will simultaneously wake up both the scale body and the module.

The sleep duration can be configured in the Personal Settings of Module B.

How do I calibrate the WeighMaster?

For Module A:
In Weighing-Timer Mode, press the Power Button and Tare Button at the same time until the dot-matrix screen displays “CAL,” entering Calibration Mode.After hearing a beep, place a 100g standard weight on the scale.When the dot-matrix screen shows the “DONE” icon, remove the weight, and the calibration is complete.

For Module B:
Go to the Calibration option in the Individual Setting, and the dot-matrix screen will display “CAL.”Wait until the dot-matrix screen zeros out, then place a 100g standard weight as indicated on the color screen.The scale will automatically calibrate and return to the settings menu, showing “DONE” on the color screen when the calibration is complete.

For Module A:
In Weighing-Timer Mode, press the Power Button and Tare Button at the same time until the dot-matrix screen displays “CAL,” entering Calibration Mode.After hearing a beep, place a 100g standard weight on the scale.When the dot-matrix screen shows the “DONE” icon, remove the weight, and the calibration is complete.

For Module B:Go to the Calibration option in the Individual Setting, and the dot-matrix screen will display “CAL.”Wait until the dot-matrix screen zeros out, then place a 100g standard weight as indicated on the color screen.The scale will automatically calibrate and return to the settings menu, showing “DONE” on the color screen when the calibration is complete.

Why doesn't my scale's display turn on automatically when l place weight on it, even though l hear a 'beep' sound?

The WeighMaster scale comes with an automatic wake-up feature. When you place an item on the weighing surface, the scale detects the weight and powers on, which is indicated by a beep sound. This beep confirms that the weighing surface has been activated. However, since the scale body and the weighing module are two separate components, the module itself needs to be powered on manually. If the module is not turned on, the display will not activate automatically. To ensure the display turns on, please make sure the module is powered on as well.
