  1. Getting The Best Results From Your Scale

    Scales are precision instruments and require proper care and skill to get the best results. Here are some tips to help you get the most from your scale:

    • Use a stable countertop or table with a level surface. 
    • Place all items on the center of the scale platform. Don't let items hang over the platform or lean against other items.
    • Zero the scale between measurements for consistency.
    • Store your scale in a safe place to prevent dust from accumulating and keep the scale secure.
    • Take care not to drop or shock load your scale. This can cause stress to the load cell and affect calibration.
    • Let your scale adjust to the surrounding temperature before using or performing calibration.
    • Do not attempt to calibrate your scale using arbitrary items such as coins. While it is commonly known that US Nickels weigh approximately 5.0g when fresh from the mint, in circulation, Nickels can range typically from 4.95 to 5.05g (&p

  2. How Digital Scales Work

    Most digital scales use a sensor called a load cell to convert a physical force (weight) into an electrical signal. This electrical signal is amplified and converted into a digital format so that it can be displayed as a weight value on the display. Sensors like load cells which convert a physical force into an electrical signal are called transducers. Speakers are another type of transducer which convert an electrical signal into a physical force by moving an electromagnet which then moves the the speaker's diaphragm to make sound. Both speakers and load cells deal with very small changes in electrical current which require a steady, noise-free power supply as well as amplification and sophisticated filtering methods to reduce electrical noise. Both speaker makers and scale makers take great care to reduce electrical noise in their circuits so that you get the most enjoyable experience out of your speaker, or measure just the right weight using your digital scale.

  3. Sources of Error With Scales

    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 b
