CALIBRATION EXAMPLES

5.1 STANDARD

(WEIGHTS)

Assume a scale of 150kg / 50 g with dual interval at 60kg. The scale is constructed with 4x 100kg loadcells
2mV/V at 5 conversion/sec with normal digital filter. The calibration procedure should be as follows :

-

Power on the FAD–4 .

-

Send scale parameters

STX ADD P 1 2 0 4 0 1 2 BCS2 BCS1 ETX

STX ADD P 2

05 15 06 BCS2 BCS1 ETX

STX ADD P 3 2 0 0 1 1 0 BCS2 BCS1 ETX

STX ADD W

Write to EEPROM

-

Wait FAD–4 to power up.

-

Empty scale and send command.

STX ADD c 0

-

Place a test weight (20kg) on CORNER 1 and send command:

STX ADD c 1

BCS2 BCS1 ETX

-

Place the same test weight on CORNER 2 and send command:

STX ADD c 2 BCS2 BCS1 ETX

-

Place the same test weight on CORNER 3 and send command:

STX ADD c 3

BCS2 BCS1 ETX

-

Place the same test weight on CORNER and send command:

STX ADD c 4

CALIBRATION

-

Place a calibration weight (100kg) on the center of scale and send command:

STX ADD b
