New HIDS Drum Scales!
Click Here to Learn More!There are times when attempting to do a calibration using the configuration software does not work. Please see
If you have the old version of the software, it is recommended that you upgrade this software to prevent any future problems when using it.
You can upgrade this software by downloading the new files from the Hardy web site at: http://www.hardysolutions.com/products/legacy-products/HI-1771WS.
If you need to perform a manual calibration to get up and running before you have an opportunity to upgrade your software, you should follow the following steps.
1. Find your block write data file location. You will need to change the value in word #32 (the 33rd word) of this data file.
2. Find your block read data file location. You will need to monitor the first three words of this data file.
3. Write a value of 0 into word #32 of the write data file and trigger the block write command.
4. Write a value of 1 into word #32 of the write data file and trigger the block write command. This will put the module into calibration mode.
5. Check your read data file, word #1 (second word) to see if bit 1 is on. This indicates the module is in Cal Mode.
6. Ensure the scale is empty in preparation for the Cal Low Command.
7. Write a value of 17 into word #32 of the write data file and trigger the block write command. This will trigger the Cal Low Command.
8. Check your read data file, word #2 (third word) to see bit 8 come on. This will indicate the Cal Low was successful. This may take several seconds before the command is done.
9. Write a value of 1 into word #32 of the write data file and trigger the block write command. This will keep the module in the calibration mode, but removes the Cal Low Command.
10. Place your span weight onto the scale.
11. Write a value of 65 into word #32 of the write data file and trigger the block write command. This will trigger the Cal High Command.
12. Check your read data file, word #2 to see bit 10 come on. This will indicate the Cal High was successful. This may take several seconds before the command is done.
13. Write a value of 129 into word #32 of the write data file and trigger the block write command. This will trigger the save command.
14. Check your read data file, word #1 to see bit 4 come on. This will indicate the Save command was successful.
15. Write a value of 0 into word #32 of the write data file and trigger the block write command. This will clear out any commands that were being sent to the module.
16. Check your read data file, word #1, bits 0, 1 and 4 should be off. This will indicate you are no longer in the calibration mode.
If any of the above steps fail, then you would need to determine the reason for the failure and correct it before starting again to calibrate the unit.
