| KD0CAC John:
Again after all this I would hope to see a mod be developed , not enough knowledge on my end , but have a new MS5308 . |

Does anyone have newer revision on MS5308 main meter PCB, time stamp 2011-05 ( or something ). IET was on rev.5 in 2011. That explains something to. |
| KD0CAC John:
I got mine through ebay a couple months ago , from China , I opened mine to check if the neg. wire was moved from the through-hole over to the SMD cap , and it was . I did not check / or remember the board vs. but will check when I get a chance , will try to post tomorrow . |

I will be making a post under the Buy and Sell forum soon but before that I'd like to first report what I found with the unit I tested regarding the power adapter issue. I watched John's video review again, specially the part where he showed the problem with resistance measurement when plugged in with the power adapter. I tried to replicate what he did. So here are my findings: --- End quote --- As I wrote previously: Do not use the original power adapter that came with the MS5308. This will possibly fry (or damage) your MS5308. Use the meter on battery power until further notice from the manufacturer. A set of AA batteries should last for a month of heavy use. Any other (linear) low ripple 12V power supply may be OK, but we dont know for sure yet |
