Have an older Fluke 4100 tried to do a calibration on it and comes up FAILED CALIBRATION. Now it wont even let me do a test, comes up saying Calibration required, was nothing wrong thought I would try it. Any answers on how I can get it to do an Auot test again with Calibrating

Thanks

The manual says pretty much what you would expect it to:

So, since you have nothing to lose at this point, I would try replacing the software in the main unit and the remote with the latest version. This will erase everything, hopefully clearing the error code in the process. Thing is, I don't know if it will let you, and of course if it continues to fail self-calibration then you really should do what the good folks at Fluke say and send it in for service. But you can find the update here: Fluke Updates

(All the usual disclaimers apply.)

I'll give up my 2500 set when they pry it from cold dead ear.

I remember on an old tester (omnipro) that you had to run the calibration with a 10-foot cable and the units stretched out in a straight line on a bench/floor. If you used anything shorter it would fail, and anything longer and the results were whacky.

Not sure if this applied but food for thought.

I just remembered something else - while I don't think these units have a "reset" button (some gear has a hidden button you can poke with a toothpick to reboot the user interface when it locks up), I believe a similiar function can be achieved by turning it off and putting it on the charger for an hour or so. Defenitely should try this first. Another trick is to take the battery out and let it sit for a day.

When it's all said and done though, it sounds like it is locking you out on purpose and no amount of cajoling it to work will change that. Even if you can force it to work, you will certainly do far better to send it in for calibration. The last time I had to send something to Fluke for repair the cost was quite reasonable, but granted that was some time ago.
