  • The software for customized instruments of other brands must be requested at: sales@microtronics.it


  • Note : In case the PC needs to be replaced/repaired, it is advisable to make a copy of the data/tests/customer archives in advance, see section “Database Backup”here


The calibration warning has expired, although the device has been calibrated regularly


  • It is necessary to download at least one test in the software to detect the regular calibration date, if the warning persists, check these settings:


  • Verify that the PC date is current and correct

  • If you have more instruments, another delivered model can be configured (see BlueForce software -> Settings menu -> About -> Model ), if different set the exact model.


Backup of saved measurements / customers (database)


In case of reinstallation of the software or to create a backup of the database (which contains customer and test data), it is advisable to make a copy of the database in an external storage:


  • In the BlueForce software, go to the File -> Archive Management -> Path menu, the "Path" shown is the default path where the database is stored (usually in the Documents folder).
  • Click on the path and then select the external drive to save to (e.g. a USB memory)


Afterwards (if it was necessary to install a fresh copy of the BlueForce software), simply copy the content stored in the external memory to the same default path specified in the software in the File -> Archive Management -> Path menu


If you want to use the database from another location, you need to go to the File menu -> Archive Management -> Select Archive and then select the database from the Blueforce folder -> Database


Modification of incorrectly assigned measures


If measurements have been stored on an incorrect closure (or refer to a different standard), they must be transferred to the correct closure as follows:


  • Rename the gate with another name (e.g. Gate Wrong input) via the Edit (right-click) context menu

  • Then create/insert the new closure with the exact name (e.g. entrance gate)

  • From the "Detail" area of the software, drag the (erroneously assigned) measures to the relevant points of the new closure


  • After this operation, it is possible to delete / erase the previous faulty shutter
