2. Setup
2.1 Battery Installation
The Tri Scale requires one CR2 battery (included). To install or replace the battery:
- Locate the battery compartment on the underside of the scale's central unit.
- Open the battery compartment cover.
- Insert the CR2 battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
2.2 Unfolding the Scale
To prepare the scale for use, gently unfold the three arms until they lock into place, forming a stable platform for your weighing bowl or ingredients.

3. Operating Instructions
3.1 Power On/Off
To turn on the scale, press the ON/OFF button (usually labeled with a circle or power symbol) located near the display. The scale will automatically turn off after a period of inactivity to conserve battery life.
3.2 Unit Conversion
The Tri Scale can measure in various units. To switch between units (grams, pounds, ounces, fluid ounces, milliliters), press the UNIT button. The current unit will be displayed on the LCD screen.
3.3 Tare Function (Add & Weigh)
The tare function allows you to weigh multiple ingredients consecutively without emptying the bowl. To use the tare function:
- Place your first ingredient or an empty bowl on the scale.
- Press the ZERO or TARE button (often the same as the ON/OFF button, or a dedicated button). The display will reset to zero.
- Add your next ingredient. The scale will display the weight of only the newly added ingredient.
- Repeat as needed for additional ingredients.
