Working Principle
This balance employs electromagnetic force balance sensor technology for weighing measurements. It utilizes a fully automatic timed internal calibration system, which calibrates using internal non-magnetic weights to ensure the accuracy and traceability of the measurement results.
Application Fields
Suitable for laboratories, research and development, quality control, and other fields that require high efficiency, precision, and compliance.
Operating Steps
1. Power on and preheat.
2. Perform automatic timed internal calibration or one-touch manual calibration as needed.
3. Place the sample on the hollow star-shaped weighing pan for weighing.
4. Use functions such as tare and zero reset.
5. Data output or printing can be achieved by connecting external devices via the RS232 interface.
Precautions
• Before use, ensure that the balance is placed on a level surface.
• Pay attention to the use of the draft shield to reduce the impact of airflow on weighing.
• Perform internal calibration regularly to ensure accuracy.
• When connecting external devices, confirm that communication parameters such as the baud rate are set correctly.
• Avoid overload use, and be mindful of overload, underload prompts, and fault alarms.
