Does it have a way to display "Peak Level" and if so, over what time period?

There is a "Peak Level" button on the front that you press to see the peak level. The peak level is the highest value recorded by the unit and can be reset by pressing the "reset button". Peak level will only record 11 ppm and over. Long term exposure to 9 ppm and over is considered dangerous.

It displays the input frequency graph in real time. So if there is a very high note, at a high output level, you will see that on the graph. Likewise for the rest of the spectrum. It looks similar to what you might see using audio programs like foobar, and such, on your PC. Basically a spectral display of what the input audio is, in relation to frequency vs. total quantity per frequency range. It appears to be based on the input purely, like most EQ's, so it's more of a pretty picture than something you would use purely for tuning your soundstage. For that, a proper SPL meter, and tone CD designed for setting up an EQ, is necessary. The old fashioned way still works the best. EQ's like this use it for more of a light show, and fancy looking effect, though it could be useful if you don't have the mentioned tools, and want to tweak your sound by ear. I could post a short video of it in action, but downloading a free copy of foobar, and looking at the EQ option, would give you a similar idea of what to expect. It basically just shows the input frequency amplitude based on the HZ, or kHZ range.

I don't think so. It has other charts but not that. I do like mine. I go to the gym. Since I move between exercises, a chart for me would be somewhat erratic. However, it does a good job of measuring my effort in three levels of intensity based on the percentage of maximum heart rate. At the end, I can see the maximum and average heart rate for the day. Good luck.

This does not show your absolute altitude but rather your relative altitude, starting from zero. At any point you read it it displays your relative altitude, plus or minus, from where you started. It also shows you the max. relative altitude that it measured.

Does your screen show its at the highest level? You might try a complete reset to see if that helps. If you do and have already set up some programs, you would lose them and have to reinput their info.

I know it a has a real time monitoring and a max setting option with the option to poll fast or slow. I do not believe it shows a min or average option anywhere. All I can get it to do is show either real time monitoring or the Max option to grab the max peak db hit. Else, the only other options are to poll the sound fast or slow, as well as set the min/max db range your testing such as 40-90db being the default range, then it increments up from there.

Not that I can see. The user manual does not mention call duration display at all.

Look for Supplement facts on back of the label. At bottom right look for :"Lot:" and "Exp".

That's a good question - will have to check my records cuz it was a while ago. Will come back and let you know!

This meter does not have that feature. It can take maximum levels, and save them but will not give you a full spectrum over a few days.

Honestly I didn't know that was an option. I really don't think there is one. I am currently at work and will try to remember to look when I get home. I assumed the alarm was preset and/or just went off when levels exceeded above normal levels.

I am not sure. I can only answer as far as how well as it has performed during the time I have had it. Maybe an email to the company?

The display shows an "overview" waveform, that lets you see where the low- and high-volume parts of the track are. It does not have a full-color waveform that lets you see individual beats.

The version I received *does* measure peak weight. You simply press the "Hold" button until the reading reads "L_p". Pressing the "Hold" button will cycle between "L_n" (No hold), "L-a" (Auto hold), "L_p" (Peak hold).

I am not very sure, if you can tell me how to check, please let me know I will try and let you know. Thanks!!!

This is not a data logger. It only tells you the high and low since the last reset. There is a reset button on the back. It is very useful to monitor the high/low in a given area. I use mine to make sure my boat engine compartment engine heater is working in the winter. I can are how cold it got when I was away. If it never reads below 40 then I know the heater is working as it should.

Not sure of your question but I'll give you some feedback. The bottom number is the total elapsed time and runs continuously until you press stop. The top number shows you the most recent split and can be adjusted to show the individual lap time or the elapsed total time for a given moment. I use it at local track meets and it works fine for me. Hope this helps.
