This Article is about: Fluke-1773, Fluke-1775, Fluke-1777 Logged Amperage results are not correct.
The Fluke-1773, Fluke-1775 and Fluke-1777 can log amperage levels that are not scaled properly, the results will show much higher levels than possible with the current probes. We have a bug in the Fluke-1770 Series firmware. We are not able to fix the data you have collected but if you update the firmware for the Fluke-1773, Fluke-1775 and Fluke-1777 to level 2.1 it fixes the issue going forward. Below are the notes for the improvements when using firmware 2.1. Below the notes is an example showing the graph levels at 250A and then the level jumps up to 3000A even though the 1500A current probes were used.
