If I remember correctly, Fluke was bought by one of the tool companies about 5 yrs ago and might moved manufacturing off shore. Since I retired I don’t pay attention anymore.
Meter leads are a consumable. They must be tested before use. Again, if you are testing to confirm something is off, maybe your life if your leads have failed.
Cheap meter story from the old days, meter with a dial to select ranges flashed over internally. I was troubleshooting in a 600 v starter. When I touched the second probe to the other phase, the short inside the meter let a high current flow that resulted in a phase to phase fault. The main 1200 amp breaker cleared the fault. The result was some small burns to the hands and forearms that faced the fault and the front of my shirt being scorched.
I always wear FR clothes now and buy higher quality meters that have been certified when doing any electrical work.
My friend spent 3 months in the burn unit from an electrical flashover. He lived with the consequences of that until he passed away 30 yrs later.
You only have one life, take precautions and use the best equipment and PPE you can. Cam
