User Calibration
User calibration is used when it is desired to calibrate the balance using a mass of known
value.
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.
USER CALIBRATION MASSES
MODEL MASS VALUE
AP110S 100 g
AP210S 200 g
AP310S 300 g
AP250D 200 g
Calibration weights must meet or ex-
ceed ASTM Class 1 Tolerance. In Eu-
rope, use OIML Class E2 weights.

Refer to the adjacent table for correct mass
values to use with the balance. For optimum
calibration, the exact value of masses should
be known. The value will be entered to four
decimal places during the procedure.
Proceed as follows:
1. Make sure there is no load on the pan
and close the chamber doors.
