12.10 Exporting and Importing Loadcell Data Points
The loadcell calibration points stored in the loadcell EEPROM may be exported to a PC, e.g. to
Windows Hyperterminal, for reference purposes. These values may be easily re-entered into the
loadcell EEPROM if the data becomes corrupt so the loadcell calibration can be reset without
having to use calibration equipment.
The data points can be exported by selecting the diagnostic mode then following the steps below.
1 Connect the RS232 cable to the PC and to the rear 9 pin socket of the machine.
2 Start Windows Hyperterminal and set the Baud Rate to 9,600 with 8 Data Bits, 1 Stop Bit
and No Parity.
3 Enter the diagnostic mode.
4 Select VIEW POINTS, select CAL POINTS then select PRINT CAL POINTS.
A report will be produced similar to that shown below: -
