To perform this, download the program attached to this support link, extract the .exe and then run the Program.
The Program will search for 8000 Series connected to the computer, on a successful connection you will see the following screen :
Press the 'Calibration Factors' button, a progress bar will appear, followed by a grid containing the current calibration factors.
To save the calibration factors, click the 'Save to File' button in the upper left menu bar. Select a location, filename and click save.
To re-load previous calibration factors, click the Load From File button, select a previous calibration factor download file and click Open.
The grid will reload with the data that has been loaded in, with the cells in a Light Blue colour.
Click the 'Save To Meter' button, the cells will change from Blue to White as the calibration factors are saved back to the multimeter.
NOTE : If adjustments have been performed, restoring the meter to a set of previous calibration factors will invalidate any calibration that has been performed.
