Fluke Norma Upgrade 4000/5000 Software

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).
