The KOIOS Electronic Kitchen Scale is a versatile and precise instrument designed for home use, offering a range of features for accurate measurement of ingredients.

Function Description

This electronic kitchen scale is primarily used for weighing food items and measuring liquids. It supports both weight and volume measurements, with specific modes for water and milk. The scale incorporates a high-precision strain gauge sensor to ensure accuracy. It also includes a Zero/Tare function, which allows users to reset the scale to zero after placing a container or an initial ingredient, enabling the measurement of subsequent ingredients without removing the previous ones. For convenience, the scale features an auto shut-off function to conserve battery life.

Usage Features

Charging: Before first use or after a long period of storage, the scale should be fully charged. The indicator light flashes during charging and turns off when fully charged. A full charge takes about 120 minutes. It is crucial to use a Micro USB with a 5V charger and a current of 2A or less; chargers with a voltage greater than 5V are not permitted. For prolonged storage, it is recommended to charge the appliance every 3 months.

LCD Display: The LCD displays various information including:

Battery indicator: Shows the current battery level.
Tare/Zero Function indicator: "TARE" is displayed when the tare function is active for items ≥ 100g.
Milk/Water indicators: Shows which liquid mode is selected.
Weight units: g, kg, lb:oz.
Volume unit: ml. The LCD may vary slightly from the depicted image, which is indicative only.

Buttons:

ON/OFF: Press to turn on, long press to turn off.
UNIT: Used for unit conversion (weight or volume).
TARE: Activates the Zero/Tare function. If an item is less than 100g, only "0" is displayed. If an item is 100g or more, both "0" and "TARE" are displayed.

Manual Shut Off: To maximize battery life, it is recommended to manually turn off the scale by pressing the "ON/OFF" button again after use. If the display shows "0" or a reading, press and hold the "ON/OFF" button for 3 seconds to turn off the scale.

Auto Shut Off: The scale will automatically shut off if the display shows "0" or the same weight reading for 4 minutes, helping to conserve battery.

Weighing Procedure:

Place the scale on a solid, flat surface.
If using a bowl, place it on the scale.
Press "ON/OFF" to turn on the scale.
Wait until the LCD displays "0" before starting to weigh. If needed, press the "UNIT" button to convert to the desired weight mode.
Load the object to be weighed. The LCD will display the weight reading.
For water or milk, press the "UNIT" button to select the volume mode and view the volume of the liquid.

Calibrating Procedure (Tare Function): To measure precise weights without removing previous loads:

Place the first load/bowl on the scale and get a weight reading.
Briefly press the "TARE" button to reset the LCD reading to "0" before adding the next load/bowl. The scale is now tared.
This operation can be repeated for multiple ingredients.
After all objects are removed, the scale may show a negative weight. Press the "TARE" button to return the estimated value to zero.

Warning Indicators:

Low Voltage Battery: Indicated by a "+" symbol and "Lo". The scale needs to be charged.
Scale Failure: Indicated by "EEEE". This means the maximum capacity has been exceeded. Remove the item to prevent scale malfunction.
