Introduction
The U.S. Solid USS-DBS71 High-Precision Analytical Balance features a wide capacity, surpassing conventional 0.1 mg analytical balances. Equipped with electromagnetic force compensation technology and a microprocessor, it ensures exceptional stability and reliability. Designed for applications requiring both high precision and large capacity, it offers a variety of functions, including summation, pipette calibration, dynamic weighing, percentage weighing, and density determination, to name a few.
While the USS-DBS71 excels in high-capacity weighing, if your needs prioritize ultra-high precision with 0.01 mg readability and a smaller capacity, consider the USS-DBS65 series.

Precautions
- Leveling the Balance: Accurate horizontal positioning necessary for repeatable measurementsand exact results. Adjust the leveling feet of the analytical balance until the air bubbleinthe indicator is centered.
- Warm-Up Requirement: For accurate results, the balance must warm up for at least 30 minutes after being powered on or after a power outage longer than 30 minutes, to reach the proper operating temperature before calibration or use.(For warm-up time details, refer to the user manual or contact support.)
- Stability: Place the balance on a stable, vibration-free surface, away from drafts and electromagnetic interference. It's important to note that high-precision balances are more susceptible to environmental factors, which can affect reading stability.
- Calibration: Calibrate the balance if it is moved (even within the same room), when ambient conditions change, and before each use. If pressing the "CAL" button has no effect, ensure you are pressing and holding it. For most models, calibration requires a long press rather than a quick tap.(Refer to the manual for specific instructions).
Error Codes
| Problem | Cause | Solution | |||
| Display not working | No power supply; Fuse damaged; Power transformer is damaged; | Plug in adapter; Replace the fuse; Replace the power transformer; lf problem persists, send the balance to the Technical Service for repair. | |||
| Unstable display | Poor working conditions; Air flow; Something between the scale pan and working table; The power exceeds its permissible value and is unstable; Static electricity; | lmprove the working condition; Close the windshield; Remove the pan and clean well the balance surface; Connect the balance to power supply 110-220V AC. | |||
| Poor accuracy | Improper calibration; The weight ofthe recipient has not been tared; Big temperature difference; The balance is not horizontal; | Double check calibration; Make sure the receptacle has been tared out; Place the balance in a suitable working environment; Make sure balance is on a flat, even surface. | |||
