Calibration
Your SPC Series scale is ready to use right out of the box. There is no need to calibrate the scale
unless you feel that the scale 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 SPC must be calibrated with the
precision test weight specified in the table below.
To calibrate the scale:
1. Remove all items from the platter and turn the scale OFF. Press and hold the lb/kg key while
turning the scale back ON.
2. When the scale shows “CAL0” you may release the lb/kg key.
3. Press the ZERO key, followed by the lb/kg key. The scale then displays “CAL1” followed by
the necessary calibration test weight.
4. Place the appropriate test weight on the platter and wait three seconds.
5. Press the lb/kg key to save the test weight calibration value.
6. Once the test weight calibration value has been saved, the scale shows an “End” message.
7. You must now turn the scale OFF and then turn it back ON without pressing any keys. Your
SPC is now calibrated and ready for use.
