Instructions
1.
Place a 15.00 lb (or 5.000 kg) weight in Position 1 and record
measured weight.
2.
Move sequentially to Positions 2, 3, 4, and 5. Record measured
weight for each position.
3.
Move weight back to Position 1 and record measured value.
4.
All measurements should fall within
•
15.00 lb ± 0.01 lb (for 30.00 lb scales)
•
5.000 kg ± 0.005 kg (for 9.995 and 13.995 kg scales)
5.
If any measured weight does not fall within acceptable range, scale
has failed test and must be recalibrated.
6.
If the scale passes all four tests, the calibration is successful.
7.
Now the calibration seals, if required by local laws, can be placed
and the Calibration Switch secured before reassembling the unit.
