Anyone have a ITW DT-830D Voltmeter?
 

Hey guys!

I was busy installing a oven for a friend tonight, when I went to test it with my volt meter, I accidentally set my meter to DCA instead of ACV, and fried a couple of resistors real good inside.

Basically, I need someone who has the same meter as me to open it up, and help me identify the roasted components, they got burnt to a crisp, and just fell apart when I tried to remove them. There are 10 components that I've found not to be working in total, and just need you to take a look at the wiring pinout / pictures I've supplied, and give me the color coded bars / close up pics of each if that isn't too much trouble :)

These are cheap testers, but I've had this one for a fair while, and its been pretty good to me. I'd rather fix it then get some new fangled one that doesn't work as well, lol

Anyways, here is a pic of the fried components, where they are located on the board, and a numbered pinout I drew up. I've probally got all of the components I need, just need to find out what the charred remains are, lol

i'm sure we something like that around here...not that i know where it is or what it is for ;)

Try this site for help with the resistors. http://www.electrician.com/resist_calc/resist_calc.htm

The Diode should have something printed on it.

I would say #9 looks like a capacitor and #8 is a transistor of some sort ( if that's three legs and not a shadow). I would go spend $35 and buy one that's close to the one in the picture and give that one a proper burial. I have an analog Radio Shack meter that's about 30 yrs. old that somebody did the same thing to but everything still works except the current scales. Good luck. :)

Yeah, I reconize the different components. I guess I shoulda mentioned that I pulled a few good components as well. There are 7 non-working resistors there, none of which I can identify. They all got burnt to a crisp, and the markings on them are gone as such. I'm sure I've already got the resistors I need, I just need to find someone with the same multimeter as mine, so they can tell me which are which. My father has one similar, but when I popped it open, it wound up being a totally different chipboard inside.

use the risitor color code. BBROYGBVGW. google it. its easy! But I would just but another one. most new ones will not blow up like that if you hook them up wrong.

Hmm.....

:)

your best bet is to save the aggrevation and fighting and buy a new one. that silicon board looks cooked too

Why not just contact the manufacturer and ask them for a schematic?

That's what I was thinking. Since it's not a gel packed board, it "is" repairable. Email them and get a schematic, or at least a parts list....:)
