![]() 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. ![]() |

![]() 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 |

![]() 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 Last edited by stj; 02-20-2021 at 02:25 PM.. |
