Nice feature though: If you are using the USB interface and you turn off the program, or disconnect the USB with the output ON, the buttons will automatically LOCK, as if you push and hold the CH1 coder wheel (hold it down to unlock the buttons). Not that nice feature though: When opening the USB interface program, If the PSU output is on with a set current and voltage, well basically it don't matter, the meter will turn the outputs OFF, and it will automatically set current/voltage /ocp/ovp to what ever the program is set to on default, in my case, it jumped from 5V/500mA to 31V/5.1A on both channels, disaster if I had just hit the output on button. SO, be really freaking careful !! |

I have been swamped and not had time to play further with the software, but IIRC, that behaviour is in the software, not the firmware. I think the software is sending the "lock" command and other settings when it first boots up. When time permits, I'm going to take a stab at creating better software for it. Particularly the program scripting. I have figured out the protocols, so it's a start... |

Sounds great, btw,with both channels set to 5v, no load I measured 5.00v on ch1 and ch2, but I "only" get 4.98v on ch3 in the 40v range. I just ordered myself a new siglent SDM3055 bench meter, Hopefully IT will be a little more "trustable" than my uni-T :D |
| Kkkkkk:
Stupid question : When I use the KOARD 3305 in series operation can I fire it up to 60 volts and in parallel up to 10 amps? Thx |
| SantaClaw:
I believe it's, 31v 10A in parallel or 62v 5A in series max output.. Yup, confirmed, only got 3a when set to 3a on CH2 and CH1 in series. |
