Just a point on the UT61E as sold by signstek as I owned one. It's flat at least to 25KHz on AC TRMS volts and is good to 50MHz on frequency. This is better than most mid-range Flukes. The RS232/IR cable that comes with the signstek one will only work on a "real" non laptop serial port and very few USB/serial bridges. Generally reasonably well built and durable. Capacitance fixture actually works quite well for testing small caps down to high pF and nF ranges. You can use it for measuring air variable caps quite happily. Continuity is pretty good - tiny bit of lag. Frequency is only good to the 22,000 counts so if you are running at say 320KHz, it will only read 320.0KHz which isn't a lot of resolution. Scopes, DMMs all suck there. Buy a counter if you need any more accuracy. Not particularly safe for high energy circuits. You have to spend 3x the amount to get something respectable in that space. However I used mine on numerous occasions on the mains to repair white goods, television SMPS etc. Good procedure is required before good equipment. Sloppy procedure will kill you even with a high end Fluke yellow space ship. I replaced mine with a Keysight U1241C eventually which is actually lower spec but safer and better engineered and orange. I like orange. I can't comment on any others as I haven't owned them. (other than a Fluke 77 and a bunch of old Fluke 8000 series which are a combination of unreliable and DT830 grade danger depending on the model) |

And just to throw more complexity into this decision after further reading I've discovered the zt301/302 which seem to be better upgraded versions of the 8002/8009 but there seems to be relatively less info on them I still have no clue which to buy |

No idea on the AN8002 front. I ordered one from Aliexpress and it didn’t turn up :( Having two meters is very useful though. |

I'm going to set £50 as my limit so what would suit me better a single UT61E or a duo of the others ? |
| Fsck:
More meters > less meters. If you build a power supply, a very common project, 4 meters are very handy to measure input/output. I'd take a duo of the others. |
