Principle
The Electronic Balance is controlled by a high-performance MCS-51 single-chip microprocessor. The weight signal is detected and processed by the Sensor to ensure high accuracy of the weighing result. With RS232C standard output interface, it can directly connect external devices for data transmission and expansion functions.
Applications
Laboratory mass analysis
Steps
1. Connect the power supply and ensure that the voltage is 220V/50Hz +/- 1Hz
2. Balance power on
3. Perform automatic correction operation
4. Set Integration Time and Sensitivity Parameters
5. Place the sample for weighing
6. Use tare weight, cumulative weighing and other functions
7. Connect the printer or computer to output data through the RS232C interface
Notice
• Power frequency 220V/50Hz +/- 1Hz to avoid voltage instability affecting accuracy
• Automatic calibration before use to ensure accurate weighing
• Avoid overload weighing, Capacity range is 0~ 220g
• Regularly clean the pan and keep the equipment clean
• When connecting external devices, confirm RS232C interface compatibility
• In case of fault alarm, check and deal with it in time
