Frequently Asked Questions

My scale displays 'OUTZ'. What does this mean?

This message indicates that the scale has lost its calibration or the load cell may be damaged. Try calibrating your scale using the steps in the user manual first. If calibration does not work, contact our warranty department for support.

When should I calibrate my scale?

Calibration is performed at the factory and many users will not need to calibrate for quite some time. If your measurements require maximum accuracy, we recommend purchasing calibration weights for your scale and checking accuracy from time to time, calibrating when needed. If you are using your scale several times a day and weighing close to full capacity, you may need to calibrate monthly or quarterly. If you only weigh occasionally and keep your scale well protected, you may only need to calibrate once a year or less. Always use trusted calibration weights. Do not use arbitrary items like coins or canned goods to calibrate. Only calibration weights are accurate enough for calibration precision scales.

How accurate is my scale?

Scale accuracy will depend on several factors including your scale's readability, environmental conditions, and calibration just to name a few. Accuracy will degrade over time as components wear down. Check our support articles for more in-depth information on scale topics including accuracy.

What is readability?

Readability is the smallest increment of the scale's display. To use a wristwatch analogy, readability would be the smallest increment of time discernable on the dial (typically 1 second), but it is not the same as accuracy. Check out our article on sources of error for information on different factors affecting accuracy.

My scale displays 'UNST'. What does this mean?

This is the instability warning. Try using the scale in a more stable location. Check out our scale support articles for tips on obtaining the best results with your scale.

  1. Troubleshooting Your Digital Scale

    Here are some suggestions and advice on what action to take if your miniscale has ceased to function properly. The manufacturer’s warranty is covered for 10 years however there are certain exclusions. Before returning the scale and spending money on postage please go through the following points:

    1. Batteries

      Check whether the scale needs new batteries and if so replace them. Be careful to properly insert the batteries in the correct manner.

    2. Calibration and Surrounding Environment

      The scales are calibrated by the factory before shipment but after travelling around the world they may need recalibration as per the manufacturers’ guidelines.  Gravity is not the same all over the world. Also scales are sensitive to drafts and vibration. The above factors mean that the more sensitive the scale, the more it may need recalibration.

    3. Abuse or Lack of Care

      If the scale has lacked TLC, has

  2. Selecting The Right Scale

    Capacity / Readability

    Scales come in a wide range of capacities and readabilities. When selecting any measuring device, you should select one which is just as accurate as you need it, but not more. For instance, wristwatches are typically accurate to only a few seconds per year while an atomic clock is accurate to a millionth of a second per day. For daily use, a wristwatch measures time accurately enough to make your appointments on time, but if you had to measure something like the speed of light to several decimal places you would want to use an atomic clock instead. However, the high costs, lengthy setup, and advanced skills required to operate an atomic clock make it out of reach for most measurement processes. Selecting a measuring device that is accurate enough for your application, but not more accurate than you need is crucial. If you purchased a scale with 0.001 g readability when a 0.01 g readability would have been sufficient, you may introduce unnecessary compl

  3. 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

  4. 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.

  5. 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
