content: I'm looking for a decent hand held DMM that does AC, DC, AC+DC and has Peak Hold (or equilavent).I've seen it in the Tenma brand but I don't actually know a DMM which has this specific "AC+DC"specification. It's not like you can search for it on a site which offers many brands and just pick outbrands thru a check-box. And then compare.I'm on a budget, so please if you know something under $200.00 US? I've done some searchingfor a budget price Arbitrary Function Generator, which I found for under $500 @ Tequipment.comwith the Instek AFG-2225 ($442.70). The reason I ask is there probably is someone who knows a goodone and can save me some time. Because there is a lot of just the AC, DC voltage in DMMs, but notthe AC+DC spec. And then there is the cheap brand names one should perhaps avoid like Temna, etc.etc. Which you can find on Ebay but I just want something better than say, "Uni-T" equipment here.Thanks for your replies in advance. You people out here in this Forum are sharp and am thankful thatI can ask this kind of question, get an answer, and reduce the brain fry that can be produced from lackof knowledge.ACvolts

content: BM867 should fit that requirement. however, with shipping and import duties, it might be pushing that budget. 867 is like 160$ usd, shipping for a bm869 (867 should be similarly packaged) like 20-30$.

content: The Uni-t 61E or equivalent is also a good dmm to start whit. It is around 60$ on ebay/shops.Mjlorton on youtube has a bunch of video's /reviews of it.

But I believe I've seen the Uni-T, but with all the extra featuresof the Brymen it's getting easier to choose the BM867.@ Frant: The Sanwa looks good but it's $200.00 or more than the BM867. The quality looks verygood though Frant!Thanks peeps. Anyone else have a DMM, please plug away here.ACvolts

content: I bought my fluke 87V a few months ago for ~160 euro on ebay in as good as new condition.In the usa it should be much easyer getting one for <200$ in good condition.I compared it to my Siemens voltage calibrators , DMM check plus and referenced against 5 1/2 digits Rigol DM3058 and it was spot on.

content: @ Fsck: I believe your right about that.I did find an obscure DMM called, "APPA models:300,303,305". But it's not made easilyavailable in the USA.In NewZealand:PDF:http://dev.avo.co.nz/images/stories/pdf/datasheets/Appa300series-DMM.pdfGood looking DMM, but expensive.

content: In your price range and even higher I would definitely go for the Brymen BM867. I have the BM869 and the main differences are that the BM867 has a lower CAT rating because of the fuses installed, it has lower accuracy specs and it does not have temperature measurements. Other that that it is the same built like a tank high quality meter as the BM869. They share the same circuit board with some different components so you could change the fuses if you feel it necessary to get the higher safety.The other possible option is the Uni-T UT71D. It does everything a meter should, but it is slow and not to be used on anything other than the workbench with low energy circuits. It has the advantage of being just $170 shipped, PC connection and software included, internal logging to 10000 points, and a 4000 count mode at 10 times a second. Just don't use it on high energy circuits. Oh yes it also does temperature. I have a UT71E.Out of the two meters I would push the BM867.

content: You know that you can calculate the AC+DC RMS voltage from the DC voltage and AC RMS voltage, right?Vac+dc = sqrt(Vac^2 + Vdc^2)Not very convenient, but an OK workaround if you only need to occasionally know an AC+DC value.

content: My head was swimming when I first started this topic.But it's getting much easier now.Yes I will be working with Higher Voltage! I believe I should get the Brymen. But it's extra for the PC-Link software and cord.It's between the Brymen 867 and the Protek 608. The Protek 608 has a lowersafety rating, Cat II @ 600v.@ Lightages: I'm very happy to know this. That the fuses just need to be changed out. Did you get the PC Link software/cord? What is the cost of that if you did and is it worth it?@ retiredcaps: Thanks for the info. Very helpful.@ alm: Yeah, eventually I would have remembered this. But do I want to do math all the time?Writing down the equation: Vac+dc = sqrt(Vac^2 + Vdc^2)@ all: With the Brymen, the 500,000 count is just excellent to have on seeing things juice up at low voltages. Build quality and accuracy level is really good. The one thing in the Fluke 87v5 has no PC Comm/Link and expect to pay more for this too if they add it in a later build. The BM869 might be just around $200.00 US, (I saw it 17?.00 EU) nope $228.31us, and it might be worth it to get the extra protection. Ones life is at stake with HV and I've felt numbing jolts before with lower Volts. It's not fun and as you get older me thinks the heart could be affected with just one bad experience. Remember seeing the movies and someone is brought back to life with the chest juicer!I really want that the only time when I need a jolt to save my life. Not take it away! It's like jumping out of a plane with a poorly made shut. Why buy sh*t DMMs? I have enough sh*t DMMs!I'm still a Fluke type of guy. The 87v is just one nice DMM and it's on the list. But I need to make purchases according to need and specs at the moment. A new Brymen is better than a used Fluke andnot working because it needs new fuses off of Bay-e.@ all: Brymen BM867 Question; How much for the cord a software, link please.The quest is getting to the end now.ACvolts

content: The Brymen 867 is rated for 600V maximum input protection (PTCs, MOVs) on the Ohms, Capacitance and other ranges. Replacing the 600V fuses with 1KV ones will not change the CAT rating of the meter or improve its safety.The shunt is limited to 15A for 30 sec instead of 20A for the Brymen 869, so the PCBs may not be exactly the same.The AC+DC voltage accuracy is greatly reduced on the 867, with frequencies above 1 KHz.

content: If you can swing it, the BM869 is worth the extra bucks. It has the higher accuracy and has temperature too along with the higher safety rating. I am pretty sure that the input protection is the same except for the fuses based on what I see the in attached image. This image is from someone on this forum I think, or maybe from mjlorton's forum.The PC connection will probably get little use from me, but I have learned that if I don't buy an accessory for something when I buy that it is usually not available when I want to buy it later. I would buy it but in the end your $200 price limit is more like $300.
