20 DC-530 Operation Manual
4.0 Calibration
The DC-530 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 in
order to stay in compliance. Your Rice Lake Weighing Systems 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 Rice Lake
