if i turn on the device, can it measure the noise level for 4 hours and store in the memory?

It does record max/min values, but it shuts off after twenty minutes. You can diasble the auto shut off, but I dont know how long the batteries will last.

You should be able to hear a noise if the unit is working. Just remember that it is not a continuous beep so you need to wait 30 to 60 seconds between the noise pulses.

Sorry I can't really answer that as I have never really used the recorder long enough to see how long a charge will last.

There is a record function button on the unit so I'm sure you can. However, I've had no occasion to try it.

Ya know I haven't tested it. I would imagine it does so if there is an event that happens definatly pull the record off of the mem card and save it to your computer.

Yes, as long as you are plug to the 12V and a card inside, it automatically records in 15 mins segments, saves and restarts new files. When the memory is full, it is programmed to over-write the oldiest files (looping). Another word, you can ride across the world many times, never need to charge and worry no juice and no memory.

Hi, this is a really cheap sound meter, it won't help you for an official meausre, also There 's no way to store data from this device.

yes, but at about 8 hours and 16minutes you may hear a slight blip as the audio track restarts - listen closely.

About 10 minutes with a laptop only plugged in - although you won't last that long, because the noise is so very annoying that you'll be shutting down pronto ;)

I would not say that, but it did return the GB to its original battery life. I can use mine for a few days now without having to charge it, probably playing 4-5 hours a day. Absolutely worth picking up.

The unit has a battery saving device built in to it.If the unit does not detect sound play on the device it will turn itself off after awhile.

The headset indicates battery level by LED light and sounds. Battery last about 5 hours of continuing use.

If it sounds, anyone can turn it off. Not sure what purpose it would serve when you are not present. The battery probably would not last several hours.

It would probably go into sleep mode while still recording but you might want to check with the folks at HP.

Sure can. It was the least expensive and works well since AI attend live bands 3x a month and last week the band was at the 85-90 mark and 8 of us told them to turn it down!!!! It can measure noise levels anywhere!Good luck!

I don't remember exactly since I stored it now but it is enough for 10 hours of constant operation in low settings.

Usually its memory keeps record of state when it was switched off. So when you switch it off at HIGH mode, it will, or at least it should go ON at high mode next time.
