Overview
JA3003 Electronic Analytical Balance is a high Accuracy, stable and multi-functional laboratory weighing instrument under the LICHEN brand. It is controlled by a high-performance single-chip microprocessor to ensure precision and Stability, and is equipped with a fully transparent sealing cover. It has a beautiful appearance and is easy to operate. It can meet the mass analysis requirements of various laboratories.
Features
1. Adopt a backlit large LCD screen with clear readings.
2. Equipped with external weight, support Automatic calibration function (external calibration).
3. Built-in RS-232 interface, which can be connected to external devices such as printers and computers.
4. With four-level shockproof design, a variety of unit conversion and counting functions.
5. Adopt stainless steel pan and built-in lower hook, which is convenient for weighing special samples.
Principle
The Electronic Analytical Balance works based on the principle of electromagnetic force equilibrating. When the item is placed on the pan, the Sensor converts the weight signal into an electrical signal, which is processed by a high-performance single-chip microprocessor to accurately calculate and display the weight result. Its Automatic calibration function calibrates the external standard weight to ensure the accuracy of the measurement results.
Applications
Research, education, agriculture, jewelry
Standards
Precision level II
Steps
1. Place the Balance on a smooth, vibration-free countertop and ensure it is level.
2. Connect the power supply (220V/5V · 2.5A, 50Hz) and turn it on to warm up.
3. Automatic calibration (using external weight) as required before use.
4. Place the items to be weighed gently in the center of the stainless steel pan.
5. Read the result after the display value stabilizes (typical Stabilization time ≤ 6 seconds).
6. To peel, press the "Tare" button after placing the container.
7. Unit conversion (g, ct, oz, ozt) or usage counting can be performed by pressing the button.
8. After weighing, turn off the power and clean the pan.
Notice
• Please place the Balance on a stable, vibration-free water platform without strong airflow interference.
• Avoid use in high temperature, high humidity or corrosion gas environments.
• Weighed items must not exceed the Capacity Range (300g).
• Handle items with care to avoid Impact pans.
• Measurement accuracy is regularly calibrated with external weights.
• Keep the inside of the pan and Draft Shield clean and wipe with a soft cloth.
• When not in use for a long time, please disconnect the power supply.
• Do not disassemble or repair by yourself. If you have any questions, please contact a professional.
