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-70 scale may be calibrated using precision test weights of 4 lb and 50 lb. The SPS-150
scale may be calibrated using precision test weights of 4 lb and 100 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.

scale. When the message “Calibration? Y/N” appears on the screen, you are in Calibration
Mode and you may release the Mexico (6) key.
