Maintaining Precision: Scale Calibration and Care Protocols

Precision scales require regular calibration to maintain accuracy. Environmental factors—temperature, humidity, vibration—can affect sensor performance over time. Professional calibration should occur quarterly, with weekly verification using certified calibration weights.

Place your scale on a stable, level surface away from air currents and vibration sources. Even minor air movement can affect readings at 0.1g precision. A marble or granite surface provides ideal stability and thermal mass to minimize temperature fluctuations.

Clean the weighing platform after each use with a soft, lint-free cloth. Avoid harsh chemicals that can damage the load cell or display. For stubborn residue, use isopropyl alcohol applied to the cloth, never directly to the scale.

Store calibration weights in their protective case, handling them only with tweezers or gloves. Skin oils can alter weight over time, compromising calibration accuracy. Verify weights annually against certified standards to ensure continued precision.

Battery-powered scales should be recalibrated after battery replacement, as voltage variations can affect sensor readings. For critical applications, use AC power to eliminate this variable entirely.
