{bought HT118A £16 delivered} Thanks Got Amazon Prime, need a 6000 count DMM delivered tonight via prime (there's a few, I'm looking at HT118A) - am no one's fool, abundantly aware that the torrents of "reviews" Amazon churns out are of as much worth as a wax kettle. :-DD So... I'm here seeking advice from those whom have amassed vast collections of DMMs ;D Oh and my budget is £30 UK. Muchos GravyBoats. |

Apprently Amazon sell a clone of the UT139C https://www.eevblog.com/forum/testgear/new-trms-uni-t-ut139c-dmm-is-available-now/msg2261307/#msg2261307 |

Thanks for the input. I got me a "Kaiweets" (straaaaange name...) HT118A - I can't work out how to measure 200Khz or 5Mhz with it, though, I seem to get no reading. Maybe I am missing something - why are there "Hz" markers on multiple range switch selections? |

The frequency count function on most multimeters is a toy at best. Use a real universal counter, or an oscilloscope if precise frequency measurement isn't critical. For one, the thresholds and amplitudes are rarely well controlled, and their behavior on complex inputs (with more than just a fundamental) is also poorly defined. |

However, seeing as the feature is there, I'd still like to use it, and so how would I achieve that please? Thanks. |
