Aneng AN8008 multimeter fuses
« on: October 22, 2018, 03:05:08 am »
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.

This raises the question: fast blow fuses or slow blow fuses?

In 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.

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 ohm
10A around 0.01 ohm.

Thanks for the help so far!

https://www.aliexpress.com/store/product/10A-600uA-fuse-for-RM101-102-multimeter/909123_32811804077.html?spm=2114.12010610.8148356.2.60fb5987OT65XM

These fuses should work for the an8008. 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.

Hi, guys! For what do you suffer with such children's fuses?  :D  Only several minutes are required to establish holders for  fuses of the standard size. I have performed such operation for  the multimeter RM101.

Sadly, the distance between the fuse holders are very small in the an8008-9 and there are some melfs and screws in the way as well.  |O

Nothing will be an obstacle if to arrange new holders as I have shown on a photo ;D

The rest of the world pays $15 shipping on mouser/RS/etc. (minimum).

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...  >:D

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. :D
Good luck to you guys in acquisition of children's fuses! |O

20mm FF rated SIBA fuses - with excess copper removed from under the fuses to prevent arc-over.
if your gonna do it - dont hold back!  :)

@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  :D

the fuses are only used for current ranges anyway.

Some people read current with their multimeter...

Thank you VERY MUCH for the link to aliexpress. 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.
