Finding More Information About Specific Models
How do I pick the right balance or scales?
Range – find out the minimum and maximum capacity required for your protocol, applications or method. If sharing the balance, consider what your colleagues range requirements might also be.
Readability – also known as resolutions or decimal places. Find out how many decimal places you need to measure or report out to.
Requirements – does your protocol, applications or method require special requirements? Here are some generic question that will help you determine if you have special requirements:
- What are you weighing? Is it a sensitive, small or big sample type, is it susceptible to static interference, or a highly viscous product that needs environmental filters?
- What environment will you be weighing in, like the lab, factory, or in the field?
- Do you have any special needs to transfer data or a need to print or export data?
- Do you have specific reporting or labeling that requires GLP/GMP/GCP/ISO compliance?
- Is there any regulatory requirement you need to comply with, like the USP or FDA?
- Do you need Legal for Trade marks like NTEP or Measure Canada marking?
- Do you need to wash it down or need it to be dust proof? IP rating
The answers to the above questions should help guide you to the proper specifications for your new weighing equipment. From our Product page, you can narrow down to the relevant category, or use the Product Selector tool on the left hand side to narrow down by specification.

Where can I find the specifications for a model?
Search or navigate to the series you are interested in on our site. Once you’re on the series page, scroll down to the Model Comparison tab to compare specs by model. If you already know the model you’re interested in, click on that link and look in the Specifications tab for the full list of specifications.

Calibration
Calibration weights are listed in the technical specifications section of the data sheet and the Instruction manual. As a guideline, two weights are recommended when calibrating your balance or scale: a large weight that tests the eccentricity of the balance and a small weight that will test for repeatability. When selecting these weights, the larger weight should have a mass that is equal to the capacity of the weighing equipment and a smaller weight that is approximately 5% of the nominal capacity of the balance.
Internal Calibration consists of a built-in test weight that is shielded and protected from external environmental influences as well as test weight handling errors. Internal calibration can be engaged at the touch of a button, or, on models that have Auto Self Calibration (ASC), calibration can be completed automatically. With ASC, the user does not even have to touch a button; the balance will automatically calibrate if the temperature changes or a long time interval has passed. External Calibration requires an external weight to perform the calibration. Because the accuracy of weighing results is affected by many small variables such as drafts, temperature or installation location, we recommend that you verify the accuracy of your balance and internal calibration weight at regularly scheduled intervals. The interval at which you need to calibrate in your application depends upon the frequency of your measurements and is based on your standard operation procedure.
Authorized A&D partners can usually provide after-sales calibration and service. If you don’t know who that is, please contact us. Don’t forget to include your model and a serial number for faster service.
Certifications
A&D is committed to the highest quality standards in its operating practices and its products. A&D is an ISO 9001-certified company, and many A&D Weighing products are certified by national and international agencies, including trade-legal bodies like NTEP, Measurement Canada and NSF. Please check the series or model you’re interested in for more information, including certificates of conformance.

Balance FAQs
The difference is primarily the resolution, or how many decimal places a balance will measure to. See the table below to see how they compare:
