To ensure accurate weighing data, one must strictly adhere to operating procedures and minimize environmental interference when using a digital analytical balance:
Placement Environment: The balance must be placed on a stable surface free from vibrations and air currents. If necessary, adjust the leveling feet using the spirit level to ensure the unit is perfectly horizontal, preventing vibrations from affecting sensor stability.
Warm-up and Calibration: After powering on, allow the balance to warm up for the specified duration (usually at least 30 minutes). Perform regular internal or external calibrations using the provided calibration weights to eliminate errors caused by temperature fluctuations and zero-point drift.
Weighing Operations: Handle samples gently to avoid exceeding the maximum weighing capacity, which could damage the sensor. When weighing corrosive or volatile substances, use sealed containers to prevent damage to the weighing pan and internal components.
Routine Maintenance: Clean the unit by wiping it with a soft, dry cloth, ensuring no liquid seeps inside. If the balance will not be used for an extended period, disconnect the power (or charge the battery periodically if equipped with an internal one) and maintain a usage log.
