Calibration (Span Adjustment)
The DC-200/300 counting scale is a high-precision instrument. Although the scale needs very little maintenance,
you may want to check the calibration after every month or so of normal usage. To do this you will need to have
a test weight of approximately the total capacity of the scale (i.e. a 10 lb weight if you have a 10 lb capacity
scale). After the scale is initially installed, put the weight on the platform and record the weight displayed. Then
every month or so put the same weight on the scale and verify that it still reads the same.
Many facilities have a technician come in and check their units with certified test weights four times a year. If
you are ISO certified, you will want to check to see if your certification specifies more stringent requirements to
stay in compliance. Your DIGI scale dealer has the calibrated test weights, expertise and experience to perform
this task for you as well as to check other operating parameters of your scale and help you effectively integrate
scales into your operations. If you do not know who your local DIGI dealer is, call us at 1-715-736-0002 and we
will help you find someone who can provide you with on-site support.
