Calibration
The DC-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 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 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.
Follow the instructions below to calibrate your DC-782 scale to ensure its continued accuracy.
NOTE:
You can exit the Maintenance Mode and return to the Weighing Mode at any time by pressing the
TARE
key. If you
have a remote scale attached to the DC-782, you must first set the SPECs for that remote scale before beginning the calibration
process.
1. Turn the scale on, then press the span switch to reset it. (See Figure 4-1 below.)
