It is suitable for customer groups with high requirements for efficiency, precision, and compliance.
Product Features
1. Fully automatic timed internal calibration/one-key calibration.
2. Internal use of non-magnetic weights ensures the accuracy of internal calibration.
3. Negative LCD screen with a clear interface.
4. Anti-static transparent glass effectively isolates static electricity.
5. Hollowed-out star-shaped weighing pan reduces airflow interference for more accurate weighing.
6. Windbreak ring design minimizes the impact of side-opening doors on the weighing pan and the balance as a whole.
7. Equipped with an RS232 communication serial port for connection with printers, computers, or industrial control devices.
8. Supports common unit conversion (g/mg/ct/oz).
9. Configurable baud rate (1200, 2400, 4800, 9600, 19200, 38400, etc.) to meet various needs.
10. Features printing functionality, allowing baud rate configuration and switching between continuous real-time, continuous stable, and single-point output modes.
11. Hardware configuration and power supply design are located in the rear cavity, effectively shielding and protecting the sensor from interference with the mainboard.
12. Supports tare, zeroing, overload, underload display, and fault alarms across the full weighing range.
13. Includes temperature compensation, time and temperature display, Good Laboratory Practice (GLP) functionality, and automatic zero-tracking settings.
14. Provides 14 functional settings, including display speed adjustment, factory reset, internal calibration time setting, peak hold, print settings, stability adjustment, external calibration, Beijing time setting, zero-tracking setting, GLP setting, counting function, percentage function, temperature display toggle, and baud rate setting.
Working principle
This balance employs electromagnetic force balance sensor technology. When an object is placed on the weighing pan, the sensor generates an electromagnetic force to counteract the gravitational force of the object. The mass of the object is accurately determined by measuring the magnitude of this electromagnetic force. Its intelligent system supports fully automatic, timed internal calibration, ensuring long-term accuracy and stability of measurement results.
Application fields
Customer groups with high demands for efficiency, precision, and compliance.
Complies with standards
Good Laboratory Practice (GLP) Standards
Operating Steps
1. Power on and warm up.
2. Set parameters such as internal calibration time, display speed, stability, zero tracking, baud rate, and print mode via the menu according to requirements.
3. Perform fully automatic timed internal calibration or one-touch manual calibration.
4. Place the item to be weighed on the hollow star-shaped weighing pan.
5. Read the stabilized weighing result, and perform operations such as unit conversion (g/mg/ct/oz), tare, and zeroing as needed.
6. For data output, connect to a printer, computer, or industrial control device via the RS232 interface and set the corresponding output mode.
Precautions
* Preheat before use to ensure balance stability.
* Ensure a stable environment during calibration, avoiding vibrations and airflow disturbances.
* Pay attention to anti-static measures by using anti-static transparent glass to isolate electrostatic effects.
* When operating the side-opening door, note the protective role of the wind ring and minimize airflow impact.
* Avoid overloading; pay attention to overload, underload prompts, and fault alarms.
* When connecting external devices, correctly set communication parameters such as baud rate.
* Perform regular maintenance to ensure sensors and the mainboard are free from interference.
* Follow Good Laboratory Practice (GLP) for operations and data recording.
