4.3 Функцыя тары
To subtract the weight of a container, place the empty container on the pan and press the TARE/CAL button. The display will reset to "0.00g". You can then add the item to be weighed into the container, and only the net weight of the item will be displayed.
4.4 Piece Counting Function
The scale can count pieces of uniform weight. To use this function:
- Размясціць якample quantity (e.g., 10, 20, 50, 100, 150, 200, 250, or 500 pieces) of the items to be counted on the pan.
- Націсніце і ўтрымлівайце COU button until "PCS" appears on the display.
- Выкарыстоўвайце АДЗІНКА кнопку, каб выбраць sample quantity that matches the number of items on the pan.
- Прэса TARE/CAL to confirm. The display will now show the number of pieces.
- Add more items to the pan, and the scale will display the total count.

4.5 Налада падсвятлення
To adjust the backlight behavior:
- Націсніце COU button to choose between C0-OFF, C0-1, or C0-5.
- C0-OFF: Backlight is always on.
- C0-1: Backlight will turn off after 1 second of inactivity.
- C0-5: Backlight will turn off after 5 seconds of inactivity.
- Нарэшце, націсніце СКАРА until the program ends and returns to 0.00.
Video: This segment demonstrates how to adjust the backlight settings of the scale, allowing users to choose between always-on, 1-second, or 5-second inactivity timeouts for the backlight.
4.6 Unit Package Locking
To lock specific unit packages for quick access:
- Націсніце і ўтрымлівайце COU button. Release it when "C0-OFF" is displayed.
- Націсніце СКАРА to choose C06-1.
- Націсніце COU button to cycle through C06-1, C06-2, up to C06-16, each representing a different combination of units.
- Нарэшце, націсніце СКАРА until the program ends and returns to 0.00.
Video: This segment illustrates how to lock specific unit packages on the scale, allowing users to customize and quickly switch between preferred sets of measurement units.
5. RS232 Interface Communication
The U.S. Solid Precision Lab Scale features an RS232 interface for connecting to a computer or printer, enabling serial data exchange. This allows for data logging and integration with other systems.
