Calibration
Using a Calibration Weight
Calibration is required when the weighing scale is initially installed or if the
balance is moved to a substantial distance from the original location.
NOTE: All calibration needs to be done in pounds.
NOTE: When setting up a new scale, do the parameter setting first.
Calibration Steps:

to show “------“, then press <TARE> to enter calibration.

Please make sure that the scale is empty first, then press <ZERO>.
Put the calibration weight on the scale. (Over 50% of capacity is ideal but
not required).
Press the “star symbol” button to enter the coarse adjust model.
Press <TARE> key to decrease or <PRINT> to increase displayed value and
stop at a number closest to the correct weight. (Note: it will not be correct yet).
Step down to a finer adjustment by pressing the <GROSS/NET> key, then repeat
step #4 and #5 as needed until the display shows the correct weight.
When displayed value is correct, press <CAL> to exit the CAL mode and
return to weighing mode.
