6.3 CALIBRATION
MENU
Your SPS scale ships from the factory fully calibrated. There is no need to calibrate the scale
unless you feel that it has become inaccurate. It is a good idea to check the calibration of your
scale from time to time with a precision test weight. Transcell recommends that you perform a new
calibration on your digital scale at least once a year.
The SPS-30 scale may be calibrated using precision test weights of 4 lb and 30 lb. Please note that
if the unit is sealed for use in commercial applications, this calibration procedure is inhibited. See
Chapter 7 for more information.
