--- Quote from: joeqsmith on July 12, 2018, 11:41:21 am ---Normally, the free HF meters are fairly accurate. The last one I showed was off a fair amount but it's the new cheaper style with no adjustment pot. I don't think I have ever seen a meter that was not accurate out of the box. Sure, they may not power up... :-DD --- End quote --- You seem to have been lucky with the HF meters. I had 2 of them that I once brought to a training session. I had to measure a resistance in the 25-30R range for verification of correct part install. Both meters read into the hundreds of Ohms. I had to use someone else's meter to check. I now have an Aneng AN-8008 and 8009, the 8009 is in my toolbag and the 8008 is a backup kept in my company van. I have them as size is a big consideration. Both measure what I need almost equal to my HP-3466A meters. And, I haven't even modified them for better accuracy. |

--- Quote from: IanMacdonald on July 16, 2018, 05:33:18 am ---Problem I find with many cheap autorangers is that they produce a series of false readings before settling on the right one. Many of the false readings look believable which causes a lot of consternation and wasted time. Thus on a cheap meter I'd generally prefer manual range setting. -How well does this one do in that respect? --- End quote --- I guess we'll have to wait for Joe's analysis (though his lab might still be missing some gear for his usual panache). |

Put a little gasoline on the LCD lens and let me know what happens. The free ones from HF have no trouble with this but so far every Aneng meter I have looked at was damaged by this. Crack open the fuses. Filled? --- End quote --- Gasoline ? What you're testing with dipping your meter in gasoline ? |

What you're testing with dipping your meter in gasoline ? --- End quote --- Because I use a meter when I work on my engines and such. I use various chemicals and sometimes things get splashed or sprayed. When I check them I have been using the fuel I use (VP C16 and methanol). I have not sprayed any with break cleaner. ANENG meters have been the worse for this test. Most meters, even the free HF meter have had no problems with this. Just to clarify, you wrote "dipping your meter" which is obviously not what I wrote or have done in these videos. |

Hi there. So there will be a test of this meter for robustness ? It will stay at the same level as one of the bigger KaSUNtest / Aneng / Richmeters ( A bunch of brands...) that was bigger KT6000 / ANENG AN860B maybe? Do it survive a controlled pulse from flyswatter? I have a new flyswatter that is rechargeable but has similar voltage (1989 Volts ) as the AA operated. |
