Have any engineers out there put a scope on the output? What does the waveform look like? thanks.

I am a retired electrical engineer so I can tell you it is not necessary to scope the output of this inverter to tell you the output looks like crap as compared to a pure sign wave inverter. It is a modified square wave output that simulates a sign wave as close as possible. The only advantage of this inverter is it is cheap and has the ability to start inductive loads rather well because it can supply the necessary current needed to achieve motor starting. I use this inverter to run saws, drills, and a small air unit in my shop. I have to pure sign wave inverters that run my home because many electronic appliances require a pure sign wave. You can look up modified sign wave on the internet to see the difference in a modified sign wave and a pure sign wave. Hope this helps in your decision making.

I'm not a retired EE, but I do own one of these and have an oscilloscope. So I think I can answer your question.See the image attached to my review for the data you seek.

That would be awesome. You can see the difference especially on high frequencies. I definitely recommend. I compared this with some others and I got the best result with it.

Same here. I think it is the auto-ranging function. Turn off the auto-ranging and it should settle down. I have zero variability when set to volts range. Given the price of the meter I decided not to worry about this glitch.

Waveform isnt displayed at all on the AERO or the rekordbox application on laptops/desktops, personally i havent updated the firmwarevin mine yet to check if the ipad can do waveforms either, but currently my response is no, sorry it doesnt do waveform at all, it's more a personal guessing game on syncing tracks in a mix as without waveform, its a lot more challenging to do so.

They have actually worked a method around it. It now needs a pulsed signal which this creates. Some types can still be done the old fashioned way by grounding it out. But I didn't have any luck and had to go with this. I hope that helps?

Metering I'm not sure, but not autofocus as it is a fixed attachment. Use your scopes focus.

Yes, I have one, but to note that this articulates has poor reception and scope. Not recommended. Better look at another brand.

Well first check you input gain but on mine the meter suddenly maxed out then dropped to nothing and hasn't worked since. That was on the first day of use. However, everything else works as it should (if a little noisy, it's not the quietest pre-amp). Since my interface has either all phantom power on or off I use the preamp for using both condenser and dynamic mics together. I don't think pinned in the red is normal.

My impression is that ranges are handled equally. That said the output is exceptionally clear and the sounds are very distinct. Don't know if this helps.

I agree with David, invest in a better tach for your application unless you're always close to shore. This (and similar items) is NOT a high quality precision product. It's a cheap solution to track non-critical service revs. Besides, I would highly doubt the readout would be bright enough on the water based on mine.

When I purchased mine I got the answer to that in the literature that it came with as a modified Sine wave. However unless you are using this for medical physics the difference between the two is minimal. I hope that helps. Mine has worked fine for running a small refrigerator and TV while we camp.

EK's answer is very close to correct. The -3dB rolloff point is 100kHz. Frequencies lower than this are possible to receive, but sensitivity will become lower as the frequency gets lower.

Bad connection??I haven't had this happen. Been using the gauges about 2 years now.If voltage is right around the cutoff of 4.5V I suppose it could blink on/off as the voltage hovers around that point. Gauge puts a tiny load on system so volts would drop, then without the load V would increase again over 4.5V so it would light up again, and the cycle would repeat.

Sounds like it's defective. I never really calibrated mine, but it seems to work fine. Sorry! Send it back

What exactly made the sound? Can you inspect every inch of the strip to check for any visual damage? I have ran mine for several hours with no issues.

As I have responded before this is an inferior piece of equipment in everyway possible. What you describe shows that. If you have time left I encourage you to return it. Amazon should have discontinued this long ago. A major disappointment to those ordering it. Originally touted by Amazon as a 1200$ fine lab instrument. So what about it AMAZON why are you still pushing this poorly designed piece of junk?

Similar results... Nice concept, but essentially a non functioning/poor quality item.. Put a meter on it and no luck... Placed into the round file... not worth the effort to try for a refund... Good luck with yours...
