13. Features temperature compensation, time and temperature display, GLP good laboratory function, and automatic zero tracking settings.
14. Provides 14 function settings, including display speed, factory reset, internal calibration time, peak hold, stability adjustment, and external calibration.
Working principle
This balance utilizes electromagnetic force balance sensor technology, achieving precise weighing by balancing the electromagnetic force with the gravitational force of the measured object. Its intelligent system supports fully automatic scheduled internal calibration, ensuring measurement accuracy and stability.
Application field
Suitable for customers with high requirements for efficiency, precision, and compliance.
Complies with standards
GLP Good Laboratory Practice
Operating Procedures
1. Power on and warm up.
2. Set parameters such as internal calibration time, display speed, and stability via the menu as needed.
3. Perform one-touch calibration or wait for the scheduled automatic internal calibration.
4. Place the sample for weighing.
5. Use functions such as tare, zeroing, and unit conversion.
6. Connect to external devices via the RS232 interface for data printing or transmission.
Precautions
• Ensure the balance is placed on a stable, vibration-free, and level surface before use.
• Pay attention to wind protection, especially when operating with side doors open, to minimize the impact of airflow on weighing.
• Perform regular maintenance to ensure the anti-static glass and weighing pan remain clean.
• When making external connections (e.g., to a printer or computer), correctly set communication parameters such as the baud rate.
• Avoid overloading the balance and pay attention to underload or overload prompts displayed by the instrument.
• In case of fault alarms, refer to the instruction manual or contact a professional for assistance.
