The best tip we can give you is to utilize a dealer not only in sourcing your equipment, but in establishing a maintenance/calibration schedule that suits your needs. This will help minimize the likelihood of any weight related inaccuracies or down time. Contact a local dealer today! In the meantime, here are some more tips & techniques to help get you on your weigh...
Did you know that many drop-shipped orders are not factory calibrated, and should be set up and calibrated upon delivery by a qualified service provider? Now you do. That's the first step in ensuring accuracy right out of the box!
Many scales have a bubble-level somewhere on them along with 2 or more adjustable feet that can be used to level and stabilize the scale prior to use. This is helpful in reducing the chance of error related to equipment relocation, barring any other significant environmental changes. Double-check the bubble after relocation to be sure the scale hasn't shifted too much or lost stability.
If you're noticing minor fluctuations in your weight readings, check for any air currents or fans that may be blowing on the platform--this DOES have an affect on readings depending on equipment capacity and resolution. Also, check for any vibration in the work surface due to any heavy machinery in the area. If you're unsure if the fluctuation is due to the environment or the equipment, try relocating to an undoubtedly stable environment and monitor for fluctuation. If the problem remains, call a local service provider.
If you're noticing fluctuation in a larger unit, perhaps a 4' x 4' platform wired to an indicator, then inspect the cable mating the equipment for any bends, breaks, or cuts. A damaged cable can appear functional, but still cause intermittent fluctuation to a large extent. If the cable seems in tact, walk the corners of the platform and compare readings from one to the next. If there is any discrepancy, or the source of error cannot be determined, then contact a local service provider for assistance.
Are your counts inconsistent or incorrect? It's important to make sure that you're following the counting procedure for your equipment correctly, and that anyone else using the scale to count is following the same procedure. Operator error can be a huge source of count related inaccuracy. If your part is small, try increasing your sample size to see if the error is corrected. A good rule of thumb is that the smaller the part you're counting is, the larger your sample size should be. Start with empty containers to be sure that you're taring them out before counting. If the source of error isn't clear, or seems to be equipment related, then contact a local service provider.
