Fluke 28ii battery compartment bulge normal?

I have a bulge! Trust me, it's no Fluke.

How so?  I've not used an 87v myself, but my 28II gives me a continuity tone the instant the probes come together or they come into contact with something that allows a complete circuit.  There's no lag at all on my unit, so what makes it less responsive?

Yes, the 28ii is good in this regard, but the 87v is a bit better. If you try, it's easy to catch the 28ii flat-footed and miss a very fast "match strike" continuity test like the kind Dave does in his multimeter test videos. The 87v is more responsive and less likely to miss a very brief connection. Perhaps it's related to the difference in the voltage used by the ohmmeter (2.8V in 87v vs. 0.5V in the 28ii). Hardly worth mentioning, but if you are hunting for differences in performance, it comes down to subtleties like this because in all other respects I find performance of the two meters to be indistinguishable.
FlyingBrickyard:
Gotcha, and thanks for the clarification.

As to the bulge itself, I've taken several pictures of my meter (which is similar to the one in the OP) and have sent them off in an email to Fluke support.

When/if I hear back I'll share their response.

Thanks, I'll be very curious what they say!

BTW, it's also probably worth mentioning that the 28ii service manual calls for 6 in-lb of torque for the battery door screws and 12 in-lb of torque for the case screws. Precision torque drivers aren't cheap and if you can't find an adjustable one with a range that covers 6-12 in-lbs you actually need two of them. This only matters if you care about following Fluke's instructions to retain IP67 ratings after opening up things up yourself.
FlyingBrickyard:
Again, good to know, thanks.

Fortunately I do have such a driver available.
