Capacitor value, can you help me?

Why ?

Graham

Because the Fluke use up battery also in OFF state. But now I am not sure that this capacitor is damaged, shoud be only a calibration?

Looks like a spark-gap device

Send your Fluke meter to Fluke service or their rep for proper service. The cap may not be the original problem. You cannot calibrate your Fluke meter yourself, without their dedicated setup, training, and factory service information.

I think it is exactly that.

Why is that? Is a Weston cell not enough?

Did removal of the capacitor fix the battery drain problem? If yes then it is likely the problem. You should be able to find a replacement from a parts vendor, or from Fluke. If not, put it back into the circuit and look elsewhere. Are you sure the battery is good? Is it possibly a rechargeable that has reached the end of its useful life?
