6. Operating Instructions
6.1 Power On/Off
- Power On: Press the power button (usually indicated by a power symbol) once. The display will illuminate.
- Power Off: Press and hold the power button for approximately 3 seconds. The display will turn off.
- Auto-Off: The scale features an auto-off function after 3 minutes of inactivity to save power. This function can be cancelled (refer to advanced settings if available, or typically by a specific button combination on power-on).
6.2 Unit Conversion
To change the weighing unit (grams, ounces, milliliters):
- With the scale powered on, press the 'UNIT' button (often labeled 'g/oz' or similar) to cycle through available units: grams (g), ounces (oz), and milliliters (ml).
- The selected unit will be displayed on the screen.
6.3 Tare Function
The tare function allows you to reset the scale to zero after placing a container on it, so you only measure the contents.
- Place your empty container (e.g., coffee cup, portafilter) on the weighing platform.
- Press the 'TARE' button (often labeled 'T' or 'Z/T'). The display will reset to 0.0g (or the selected unit).
- You can now add your ingredients, and only their weight will be displayed.
6.4 Timer Function
The integrated timer helps you track extraction time for coffee brewing.
- Start/Stop Timer: Press the 'TIMER' button (often indicated by a clock symbol) to start the timer. Press it again to pause/stop.
- Reset Timer: Press and hold the 'TIMER' button for approximately 3 seconds to reset the timer to 0:00.

6.5 Auto Modes (Espresso & Pour Over)
Comparison of Auto Tare & Timing mode versus Manual Tare & Timing mode on the scale.
The scale features two auto-modes for simplified brewing:
- Espresso Mode: Designed for espresso extraction. Typically, this mode will auto-tare when a cup is placed and auto-start the timer when the first drops of espresso hit the cup.
- Pour Over Mode: Optimized for pour-over brewing. This mode may auto-tare when a carafe/dripper is placed and auto-start the timer when water is poured.
- Activating Auto Modes: Press the 'MODE' button (often labeled 'ESP' or similar) to cycle through manual mode and the available auto-modes. The active mode will be indicated on the display.
6.6 Buzzer (BEEP) Prompt
The scale includes an audible buzzer for certain operations. This can be turned off if preferred.
- Refer to the specific instructions on the product packaging or a quick start guide for the exact button combination to toggle the buzzer on/off, as this can vary.
6.7 Calibration
The scale is factory calibrated. If you suspect inaccuracies, manual calibration may be performed.
- Calibration Procedure: Typically involves powering on while holding a specific button, then placing a known weight (e.g., 500g or 1kg) when prompted. Refer to specific instructions for your model, as this is an advanced function.
7. Maintenance
The waterproof surface of the scale is easy to clean with a damp cloth.
- Cleaning: The scale features a waterproof surface, making it easy to clean. Wipe the surface with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water.
