Fluke 666438 Positive Battery Contact
The 666438 is a small internal spare part for the Fluke 789 ProcessMeter. It is the positive battery contact, meaning the part that provides the electrical connection on the battery side when the instrument is powered by the four AA batteries in the battery compartment.
This type of part is chosen when a contact is worn, bent, or missing, and you want to restore the instrument to its original factory configuration. When servicing a measuring instrument like the Fluke 789, it is important to use the specified spare part because the battery contact must fit precisely into the holder and connection in the instrument.
For a customer with a Fluke 789, this is therefore not a general accessory, but a specific spare part belonging to the battery section of the meter itself.
