How accurate do you feel this power meter is? How would you rate it on a scale of 1 - 5 with 5 being very accurate.

If you can get it to work properly. I would go to your local golf shop and ask to hit some clubs and check your speed like that. Most all golf shops will help you out. That is what I do, because you can not trust the medicus power meter.

I thought it was accurate , to a 4. You might not like the results, but swing fast ,not hard. But it goes thru batteries fast.

I have not had any problems with the meter, I am not sure what you are wanting to check the frequency of, but I use it on HVAC equipment and check frequency once in a while and it works for checking that.

My answer would be a big YES... it seems very accurate and I often compare it to the one my Step-mom uses daily at her Hospital job.It's consistant within 2 or 3 percent. My husband and I are in our late 50's and we both use it once every morning...again after our daily workout at the Gym...and again a few hours after the Gym workouts. six times a day and it has never failed to give good solid readings.

It was not very Accurate. Also... my third purchase was a bad unit. Neither the seller nor the maker would respond... not even to the BBB. Be careful. The working two have lost most battery life after a year. Good luck.

I find that this meter works great and is accurate for my indoor and outdoor shoots. It measures only the flash and not ambient. It does have its quirks, if I need to meter lower power then f4, the meter seems to be not sensitive enough to get a proper reading. So I have to swing it a bit. With higher flash power as in f8 or f11 mine is very accurate. Hey its what we get for being cheap! We could saved a hundred more bucks and got a very decent meter, but this one does work for me. Try maby metering for the ambient with your camera and then meter the flash. Dont know if this helps but mabe it will be usefull to you.

I would say it is fairly accurate. I compared it to my more expensive Radio Shack and the numbers are very comparable.

I doubt that it is "accurate" in terms of being calibrated to any significant extent. I just line the up the disk to where I want it and it is very close to my floor pumps reading. I just use it to finish my ride if I get a flat. If I'm within 10 psi I'm happy enough to get home.

The meter is not symetrical, and one side must "face" the source of power, as outlined in the directions. Double check you have that right. From your description, I don't know how you have the panels wired. I would suggest you test only one panel at a time, and see if it produces 80% of it's rated power output when in direct sunlight and when the system is under a load. You could have a defective panel, a short, etc. (I'm assuming that you have already tested the meter using just the battery and a load and know it's okay)

I've found it very accurate. As you dial in the temperature it displays and once set, the current temperature is displayed, a "heating" light comes on until it reaches the selected temp. It heats very quickly and holds within a few degrees during all operations that I've done. I've used it as high as 400 degrees with no issues.

The unit itself has no power-consumption rating that I can see. If I had to guess, I'd say it consumes probably as much power as a night-light, or less. The unit itself is basically a volt/amp meter coupled with a display - none of these are power-hungry components.

It bases power on heart rate with an algorithm so calibrating it won't make it more accurateDo google searches for more info about how it figured out power what it assumes about the workout they estimate that it is within 15% of a real power meter but it can be +/-

the spec says 3%. But on my unit i just received I just made the following measurements using multiple professional HP and Fluke high accuracy instruments (I'm an electrical engineer). TS-836A said 122.3V, instruments said 122.5V; TS386A said 769mA, instruments said 725 mA -that's a 5% error. Predictably the Watts was off 5% too as it is just a calculation. I'm about to leave a comparison against the Kill-a-watt in the reviews

I've been using it side by side with a digital usage meter provided by my utility company (SMUD) and it is always within 30 Watts (shows 30W less). Not a scientific test though :).

Yes, I am busy using it to indicate the charge coming from a bank of solar panels. I am going up to a max of 42A (using the 200A shunt) - it does not seem to give a reading at low currents e.g. 1A but once it goes over this it is pretty accurate. I am using the battery that I am charging as the supply and it works fine.

Yes, the meter reads from 0 to 150 watts. My rig is just like yours in output and this meter works fine.

Right around .50 Ah ...not very much at all considering... I was worried about it drawing too much energy from my solar panel charging system, but its pretty negligible...you could always throw a toggle switch in there to save battery drain if your worried about it. Ive had no problems with it on my system for three years running now...just on here getting another one for a friend! I use one around the shop too for a portable voltmeter... the accuracy is right on the moneynwith my 89$ voltmeter at work...hope this helps, and I do recommend!
