Some Norma 4000 and 5000 instruments require attention due to a calibration error of the external probe (EXT.Shunt- BNC) inputs of instruments caused by incorrect data being written into the instrument at production.
This error only affects the current probe inputs of the instruments in the 100mV range and only specific serial numbers (you will have been contacted by Fluke if this affects you).
Please follow the steps below to fix the calibration data for all customers if you have been contacted to do so by Fluke.
Select the Device Port you use for the connection and click on Connect.
Make sure that the settings on the instrument are 115200 8/N/1 HW
and click OK
When the program has finished you can use your instrument without any insecurity.
