User Calibration User Calibration User Calibration User Calibration User Calibration
User calibration is used when it is desired to calibrate the balance using a mass of
known value.
NOTE NOTE NOTE NOTE NOTE: Before beginning user calibration, make sure masses are on hand.
If you are in the calibration menu and
realize masses are not available or you do
not want to calibrate, exit the menus and
return to normal weighing.
Refer to the adjacent table for correct mass
values to use with the balance. For opti-
mum calibration, the exact value of masses
should be known. The value will be entered
to four decimal places during the proce-
dure.
Proceed as follows:
1. Make sure there is no load on the pan and close the chamber doors.

8. Repeat steps 6 and 7 and set the numbers to match the value of the selected
calibration mass.
