Help Identify this Fuse

**bohaboha** · 02-19-2021, 07:07 PM

Hi everyone I have a multimeter model: BS1901W that no longer works it has a very strong yellow fuse that has no designation so I wonder if you can help me know what value it has. Here are some pictures

pics are rather blurred

Yellow PTC? Shouldn't affect power up of the meter...

It doesn't have any fuses, only a yellow PTC to protect the 200mA current range.

no, the yellow thing is a polyfuse.
tell me what's printed on it.

the meter looks like a Centec btw - worth about €3 if you break it.

hello all there is nothing printed on it-i tested but no continuity
i will try to have a better pic later today

when you say the meter doesnt work - be specific.
does the display show anything?
does it read volts?
amps?
continuity?
all these modes use different circuits

oh yes there is something on it LBV160 and fuse on the bcb.not working att all

**redwire** · 02-20-2021, 01:44 PM

Post a picture of the part that is the "fuse LBV160". Without the bblluuurrr.

It seems to be a custom British Standard multimeter made by Caltek HK.
I call a polyfuse a PTC, the big yellow squarish one looks to be for 200mA current range.

I still say there's no fuse- "self-recovery fuse protection" in the marketing. You would think any fuse would be replaceable, not soldered in for a multimeter.
There are three bead style PTC's, and a MOV - but I can't see any fuse.

found it.

it wont stop the meter working, it will just mess up the current readings usually

hello redwire in terms of better pictures I use my mobile because I do not have better right now

**bohaboha** · 02-20-2021, 04:44 PM

hi stj you are right after replacing better battery now it works but not as it should i have to test some more to understand.so that fuse it does not stop the multimeter
