Scales are precision instruments that are sensitive to changes in the environment and exposure to foreign substances (e.g., dust, dirt, moisture, etc.).
Try to keep your scale clean of any foreign substances as they will begin to seep into the electronics of the scale, causing erratic readings and eventually causing complete failure.
Avoid lengthy exposure to extreme heat or cold.
Do not store your scale in a car or other locations where extreme temperatures are likely to affect the device.
Allow your scale to adjust to room temperature prior to weighing. If your scale is too hot or too cold, this will cause your scale to “creep”. In this case, weights will continually increase or decrease as the load cell becomes adjusted to the ambient temperature (e.g., 0.1, 0.2, 0.3…).
Changing the batteries and calibrating the scale routinely will also prevent faulty readings and will help maintain the integrity of the scale.
