16 DMC-782 Operation Manual
4.0 Calibration
The DMC-782 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 it is preferable 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). If
the reference weight is not equal to the full capacity of the scale, it must at least be greater than 10% of the full
scale capacity. For instructions on how to calibrate the DMC-782 using a test weight equal to the full capacity of
the scale, see Section 4.1 below. If you are calibrating the scale using a test weight of less than the full capacity,
see Section 4.2 below.
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 RLWS 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 Weighing Systems dealer is,
