content: Has anyone found a place to buy fuses for the AN8008 at a reasonable price? (In my case postage and taxes on it is high from major suppliers.)Fuses are glass fuses with white content, diameter 3.6mm length 10mm. 0.2A and 10A. I assume quick. I have not meassured the resistance yet.GeirSent fra min EVA-L09 via Tapatalk

content: Quote from: Mr. Scram on October 21, 2018, 06:34:04 pmIn multimeters you always wants fast blow fuses. They are not supposed to handle any over range inrush current, but blow before the shunt or protection diode do.

content: I have ordered the 10A fuses, linked to above, from Ebay, let us see what they are.It is difficult to find QUICK 0.2A fuses.Bying from Mouser is an option, but the postage causes them to cost about the same as a new AN8008.I meassuerd the fuses in my AN8008:0.2A 0.80 ohm10A around 0.01 ohm.Thanks for the help so far!GeirSent fra min EVA-L09 via Tapatalk

Richmeter and aneng meters are supposedly made by the same OEM if i recall correctly. The 200mA seems to be $0.96 shipped for me.

content: I think since it's common sense not to use these meters on high-energy circuitry, it's like shooting cannons on birds to replace the existing fuse sockets in order to be able to install real HRC fuses, if suitable ones are available (just ordered a mix of 30 3.5*10mm fuses shipped at the price of one HRC fuse). I consider these fuses inside these meters rather as a means to protect the meter from stupid mistakes of the user and not the user from potential explosion (of the meter)/ injury. If there's chance for the latter to happen, the user didn't quite understand something...

content: TurboTom, I only suggested one of methods to get rid of children non-standard fuses. It is possible to use fuses of the standard size, it is possible ceramic, it is possible from glass which roll near at hand in a large number.Good luck to you guys in acquisition of children's fuses!

content: @indman The situation for me is like that: I must have got about a total of five of the tiny meters (different models) distributed in my home, car and field-access tool box so it's never far to get one, simply since they are so versatile. Actually, I never blew a fuse on any of these. But to me, it's just too much hassle to replace all the fuse sockets in all of them. I rather spend ten euros on 30 suitable "children"fuses of different ratings and put them in the magazine so I've got spares just in case.For mains work, I anyway use one of my two Flukes or maybe the surprisingly well made Peak Tech 3440 (CEM DT-989).Peace

I will try them.Compared to other sources this will probably be 1/10 of the cost compared to main streem suppliers, the shiping cost far too much.If they are bad, I will modify for longer fuses.I have been aware of the high voltage issue with these short fuses, but I have other meters for that purpose.GeirSent fra min EVA-L09 via Tapatalk

content: I think it's the chinesium plating, it oxides and makes crappy contact. The slit makes a sharp edge that chews up banana plugs I find.These pics of "gold" banana jacks are just sleeves. Probably plated steel.A rich man would findMill-maxor something that ends up costing more than the DMM.The AN8008 rotary switch is still shit, it's always oxidizing and not reliable.

content: You get these sockets from Hirschmann (brass, gold plated, AC/DC 1000V, 32A, CAT II, contact resistance 5mOhm, threaded connection) e.g. at RS components. The black one has order no. 972354-100 (other colors red -101, blue -102, yellow -103, green -104 and yellow/green -188 and some more colors). And there is a version with 6.3 x 0.8 tab connector (order no. 972356-1..). With the order no. it should be easy to find other suppliers.

content: It is a TVS and my pic has SMBJ6.8CA although the pc board says "4007". Problem can be the high capacitance upsets pF capacitance measurements- unless that is correctly nulled out in the EEPROM.
