| Mr. Scram:
I see it has a bar graph. That could actually be interesting. |
| stj:
the real questions, what chip does it use, and does the led circuit use a boost convertor or a resistor? because the older meters light a lot dimmer on rechargeable batteries. |

I also spotted this meter as "Richmeter RM409B" https://fr.aliexpress.com/store/product/RM409B-True-RMS-Digital-Multimeter-Button-9999-Counts-With-Analog-Bar-Graph-AC-DC-Voltage-Ammeter/909123_32878214801.html?spm=2114.12010612.0.0.792b41f1t0Su4P Here another view of this meter: https://cloud.video.taobao.com/play/u/17300505178/p/1/e/6/t/10301/50143362094.mp4 Display looks good, but I won't buy a DMM which sucks the batteries empty faster than a vampire could. I'm kind of intrigued by the UI from rotary switch to push buttons. I never liked the big rotary switches on DMM's. But I also don't like to push a button a gazillion times to select between funktions. My ideal UI would be a push button for each funktion, like a lot of the benchtop DMM's do. I am curious about an in depth review of this thing though. I really would like to know which chip is in it and how they do the switching between the different functions. |

Overall I don't think this meter is more button pushes than before. It looks like it actually might be less overall. (and how many button pushes equals one use of the dial? Dialing is often a two-handed operation) --- Quote from: Doctorandus_P on June 04, 2018, 01:12:47 pm ---I'm kind of intrigued by the UI from rotary switch to push buttons. --- End quote --- |
