Меры предосторожности

• Always operate the balance on a stable, level surface.
• Avoid placing the balance near strong electromagnetic fields, vibrations, or air currents.
• Do not overload the balance beyond its maximum capacity of 110 g to prevent damage.
• Use only the provided UL-certified power cable.

• Не пытайтесь разбирать или ремонтировать балансировочный механизм самостоятельно. Обратитесь к квалифицированным специалистам.

Настраивать

1. Распаковка и размещение

Carefully remove all components from the packaging. Place the balance on a sturdy, level, and vibration-free workbench, away from direct sunlight, heat sources, and strong air currents (e.g., air conditioning vents).

2 Сборка

• Place the weighing pan onto the pan support in the center of the balance.
• Assemble the draft shield around the weighing pan. Ensure all panels are securely in place to protect against air disturbances.

3. Выравнивание

The balance must be perfectly level for accurate measurements. Adjust the adjustable feet at the bottom of the balance until the bubble in the spirit level (located on the front or side of the balance) is centered.

4. Подключение питания

Connect the UL-certified power cable to the 6V DC input port on the rear of the balance and then plug it into a suitable power outlet.

5. Время разминки

After connecting to power, allow the balance to warm up for at least 30 minutes before use. This stabilizes the internal components and ensures optimal accuracy.

3. Функция тарирования

To subtract the weight of a container, place the empty container on the weighing pan and press the 0/Т (Tare) button. The display will reset to zero, allowing you to measure only the net weight of the contents.

4. Калибровка

Regular calibration ensures the accuracy of your balance. It is recommended to recalibrate if the balance has been moved or if accuracy is critical. Refer to the specific calibration procedure in the full manual for detailed steps. Generally, this involves pressing the КАЛ button and following on-screen prompts using the provided calibration weight.

5. Функция подсчета количества штук

The balance includes a piece-counting function for counting multiple items of uniform weight. To use this feature:

• Поместите известное количество sample pieces (e.g., 10, 20, 50, or 100) on the pan.
• Нажмите НАБОР button and follow the instructions to input the sample количество.
• Как только сample is registered, remove it and place the bulk quantity of items on the pan. The display will show the total count.
