There is a setup, just not via some button (hold setup while switching it on). There you can (like with about all keysight ones) change the setting from auto AC to auto DC voltage when turned on (who wants to have it on AC automatically anyways?). Also when you do the continuity test thing, whenever it doesnt work "fast" enough, you should redo it with high quality probes. It is almost always the probes. 1242B probes are crap, continuity almost unusable with them, using proper ones there is no problem at all. Also I think in the setup you can enable auto hold (try to have a look at the manual this time)
@alexanderfefer83762 жыл бұрын
Hey Dave, great teardown. Just wanted to point out that the meter does indeed have auto-hold - you need to enable it in the setup menu (hold down the orange button while turning the rotary knob). It's worth looking through the manual, there are a *lot* more capabilities in this meter than are immediately evident from a glance at the front panel.

Reason why not put BT inside the device is that that way you don't need to get the thing certified in every single country you import it to.

The globbed up inductor might have been to help prevent -any- moisture from altering its characteristics over time... as pure copper wire is not a happy camper with any sort of moisture. I'd imagine that the chemical make up of all the guts and bits would favor the copper in that inductor as a potential anode for corrosive processes (sorta like how the zinc sacrificial anodes save a ship, this inductor could try to do the same?). Like... maaaaybe its another stab at making the unit a bit more robust in marine environments.. say a drop or two of water gets in during a fuse/battery change, ect. I think someone was thinking about longevity to an extreme.

+Keith MacDonald that coating is only so thick and doesn't necessarily coat the entire surface of copper, like around where the heat of the soldering melts it away. I've seen audio amps out of vehicles that have suffered water intrusions and the inductors sometimes have a bit of corrosion them where things were just right. I agree totally, its not necessary by any stretch because of the insulation barrier, just overkill. But at the same time, we are taught not to necessarily trust that barrier is complete. Maybe its another reason relating to someone wanting an extra barrier, but that would be beyond me.. this stuff is sadly only a hobby for me, took the wrong career paths while I had the money to do so (d'oh!)
