content: waaaaaaaaaaayyyyyy to much rangesand the 1khz for what ?? the frequency response ?? we have meters up to 100khz now ...the zt303 is more apealing to buy in my case

content: Quote from: 001 on January 17, 2019, 08:56:15 pmo/ZT303 appears to be the same RM219/AN870 in another case.My question about these DMM is:Can they replace a Uni-T UT61E?* Ignore protective factors, 99% of my bench use is with continuity and low DC voltages.Have a good response time / continuity? (Main factor for my use in the bench)Does the integrated TRMS converter have superior performance? (compared to the traditional AD737)Not having trimpot adjustments, is it a good, bad, or indifferent factor?

content: Can they replace a Uni-T UT61E?- It is not so quick as UT61EHave a good response time / continuity? - Yes, buzzer is fastDoes the integrated TRMS converter have superior performance? - it is ok up to 1kHz. It is voltage divider problem I meanNot having trimpot adjustments, is it a good, bad, or indifferent factor? it is FAAAR better than trimpots

content: With the number of divisions on the bargraph, I wonder if it is the same hack as the Surpeer AV4 - segments are grouped five by five and they update at the same rate as the measurement.The range switch is indeed weird on the ZT-M1. At least theZT-M0seems to thorougly admit its manual range nature.If it weren't for the price, I would love to compare them to the others I have here... (I can only have so much money to spend with my hobbies).Quote from: 001 on January 21, 2019, 12:32:28 amI agree. The UT-61E is a good meter, but the trimpots tend to be its Achilles' heel if the meter is submitted to abuse or wide temperature swings. That and the always lingering possibility of a simple ESD spark kill it (as tested by joeqsmith). Otherwise it is a great meter and had been serving me very well.

content: Why don't we see more of the DM1106EN based ones? It's newer and capable of more. Maybe china just has millions of the 0660's stockpiled
