There are a number of forces that can affect the accuracy of a weighing result. All measuring devices deal with measurement error to some degree. Measurement error is the difference between the measured value and the "true" value. Some of the factors affecting measurement error with digital scales include:
- Environmental Factors - Scales need to be used in a stable location, free from vibration, wind, and fluctuating temperatures. Scales perform best at room temperature and perform especially poor in cold temps. If you recently brought your scale out of storage or received it from the delivery man, you should let it adjust to the surrounding temperature for at least an hour before use. Rapidly changing temps can cause the weight readings to "creep" or drift in one direction.
- User Error - Operator proficiency also plays a role in measurement accuracy. Being consistent with your measurement technique and knowing your scale's capabilities can all contribute to better
