They ran out of positions on the rotary switch for 9mA and 99mA ranges. You have to switch to a mid-shunt (R24, 1R) which is already on the PCB. Right now its 0.010 \$\Omega\$ or 100 \$\Omega\$ shunt only. The DMM IC supports these ranges, have to hack the rotary switch and add CAL factors to EEPROM. |

That's why I'm down to these absolutely ESSENTIAL few from *mumblety-seven* that I USED TO have. :-DD in other news... my spaghetti 17B meter arrived today, along with a brand-new new radiator for my Franken-Cruiser. Both delivered to my door a day early, and a total cost of less than $65. How the hell is that even POSSIBLE?!? :-// In all honesty, the spaghetti 17B has quite a bit more "quality" feel than even my old "backup" $99 Sperry; that cheap vinyl boot makes a helluva difference. Large, crisp numbers, but not the broadest viewing angle... however, still easy to read even with my glasses off. I'd like a longer BL timer; but then, I'd prefer 4 AA power to support that with tolerable battery life. It's rated 1000VDC/600V Cat IV on the front with a 250V rated Fuse inside; I suppose if you stuck the leads up 4 cats' arses and probed with their noses you might could measure that with some theoretical measure of safety. :bullshit: Anyhoo... my only regret now is that I didn't buy 10 more to sell; guess I'll have to fund my soldering station habit some other way. :palm: Cheers, mnem If we save the whales, where will we keep them? |

There are no formal schematics, I traced one out and it is pretty much the datasheet with an external Vref IC: Some are translated, if you search the web. https://www.eevblog.com/forum/testgear/new-aneng-multimeter/msg1279811/#msg1279811 |
