User questions & answers

Question:	noisy neighbor issue. Could I set this outside and have it record sound levels overnight 6-8 hours and it would capture sound readings over that time
Answer:	Dear Customer, The item could be capture the MAX or MIN sound level overnight 6-8 hours,but can't record all dynamic data.
Question:	Does this have c weighting and slow response options ( for calibrating monitors
Answer:	Yes it has C weight and fast and slow
Question:	My neighbor is a tire company there business is fenced off, they use compressed air all day, will this pick up the decibels at approx 300 feet away
Answer:	It will read the ambient sound level, and the compressor will be part of that. It shouldn't matter what the sound is at 300 ft. Get a copy of your town's noise ordinance; work with the cops, if that is not satisfactory, lawyer up.
Question:	How accurate is it? Can one rely on the readings
Answer:	The one I have seems pretty accurate, comparing the readings to a minidsp umik-1 they are very close. Assuming the umik-1 is calibrated correctly I would say decently accurate.

User questions & answers

Question:

what does it mean how does it work.. does it have actual alarm that? "with Backlight Alarm" term what is it

Answer:

Hello thanks for asking. Yes, our sound level meter has back-light alarm function. "Back-light alarm" means when measured noise exceeds the value you set, the backlight will flashing. Say you set 66dB as the threshold, when the sound exceeds 66dB, then the backlit will flashing. By the way, you can also disable the auto shutdown function, then sound meter can continuously reading sound until you turn it off by manual. Hope this information can help you.

User questions & answers

Question:	Which Windows operating systems is this software compatible with
Answer:	I have never been able to get the software to work under Windows 10 Pro. It never recognizes the device. I spent many hours trying to get it to work. I tried to get it working on my 8 core desktop, a Microsoft Surface Book, and a Surface Book 2 when I upgraded. I also emailed back and forth with support several times. They tried their best to help, but none of their suggestions worked, so I finally gave up on using the Windows software with this device. It's a shame because the PC connection is one of the reasons I chose this device over other brands. Of course, by the time I gave up, it was well past the return period. Fortunately, as a stand-alone device, this meter works very well. So, even without the PC software, it's a great value. In fact, despite the software issues, I'm still pretty happy with this meter. I hope this was helpful.
Question:	Are these calibrated before they are shipped
Answer:	According to directions it is well calibrated before shipment and recommends recalibration cycle of one year. Directions tell you how to recalibrate. Seems to be working for me/
Question:	Does this show average volume? Concerned that the readout will change too quickly to log the general reading
Answer:	Hi there - I am with BAFX Products Support.The previous answer is correct. There are two modes. The first mode simply reads the noise level at a constant rate, continually flucuating as the noise level changes. The other mode as she mentioned is the "MAX" mode. When you set it to this mode it will hold the highest reach noise level since placing the meter on MAX mode. There is not a mode that will give you an "average" reading for a period of time.If you have further questions, please do not hesitate to contact us.Regards,BAFX Products Support
Question:	Will this meter really go down to 30dBm? I bought one that said it would but when I got it it only went down to
Answer:	Hi there - I am with BAFX Products Support.It can certainly reach 30dBa however to find a location where the sound level is that low you will need to work very hard. Even most "VERY quiet rooms" are going to have a readings of anywhere from 35-45dba.Using it in a room of a house away from any busy streets, with all windows and doors closed, all ventilation off and all air ducts closed and no humans or animals in the room, MAY allow you to get down to 35dBa or so. Reaching a level of 30dba is going to be extremely difficult for most people unless you have a sound proof room.Regards,BAFX Products Support

User questions & answers

Question:	How well will this work to measure the sound level in a car cabin
Answer:	IT can work fine. When turned “on” it displays an internal reading that appears high. Ignore this reading because the car read is probably higher.
Question:	Can you program this to beep or alarm at a certain noise level
Answer:	no you can not program it at all. it just has the microphone on top to pick the noise up and then shows you on the display what the noise level is.
Question:	Does it lock to the loudest sound? , if I wanted to check the db of a gunshot for example
Answer:	I'm not sure what you mean "lock" but you can check for the loudest db very easily, and the lowest db, too. It doesn't stay on that number forever though. Or at least I haven't gotten it to do that. But I'm usually too busy trying to figure out the average db's. I wish it told me that. It cycles off after so long (maybe 20 - 30 min.) and then you've lost all the data.
Question:	can this record noise over a certain period of time
Answer:	No, this does not record, just measures the decibels of the noise

User questions & answers

Question:	Is it normal for the device to measure 47 dBA in a quite room out of the box
Answer:	47 seems a bit high, but listen to what is around you. There may be things that you've grown accustom to and therefore 'tune them out'. If you have a large closet with a fair amount of hanging clothes (they absorb a lot of noise), try it in there. In my case I get 38-40. Also, holding it can make a difference. What do you get if you put it on a tripod? I had an opportunity to compare mine to a pro-quality unit (> $2,500) in a sound room, but didn't think about it at the time given the rush to get things done.
Question:	Why is it Not calibrated at factory
Answer:	Dear Our products are calibrated with standard sound sources before leaving the factory, because in a quiet environment it does not mean no sound. You can rest assured that our products are professionally tested and calibrated. Please feel free to purchase and use.
Question:	Would this be good at measuring sound spikes or just ambient noise? For example trying to measure a gun shot at the range
Answer:	Yes. It can be set to track the highest sound and hold that measure so you can review it.
Question:	Do these meters conform to ansi si
Answer:	Unfortunately I am not able. The product information is very vague but then again it was very in-expensive. I'm using it for general measurements. If you're looking to meet ANSI then I suggest you spend the money and buy an appropriate product from a more scientific company. No slam on Meterk but they appear to sell a wide variety of products. You may wish to consider Amprobe SM-10 at $172 as it seems to meet ANSI, IEC, JISC (Japan) and N10140 (Australian) standards

User questions & answers

Question:	Does this meter do dbC weighting in addition to dbA
Answer:	The instruction booklet describes only “A” weighting. There is no reference to dbC mentioned.
Question:	what does weighing a+unit mean? what is a triangle bracket? thanks
Answer:	triangle bracket is I believe is referring to a tripod like for a camera ,
Question:	what about its warranty
Answer:	From the warranty card included in the box: Within 30 days - return for full refund; 30-90 days - will replace defective unit with a new one; 90 days to 6 months - Will replace unit with new one. If registered on tacklifetools.com - receive extra 3 months warranty. Contact [email protected] for RMA #.
Question:	Where is this product made
Answer:	"Made In China" ... that is what is molded on the 9v battery door. Not sure why that really matters as it seems that 80% of the world's products come from China. If we were a bit more tyrannical, empirical, communistic methods then maybe we could compete but who wants to make products where we poison the community, the workers and their minds. I remember where things were "Made in the USA" and if it came from another country it was like "wow!" really? Back in the 60's, anything German and Japanese had a great reputation ... so where where we? oh yes ... I have one and it works and its cheap and its made in China. I hope this helps

Vivid Simulated Indication

• With simulated indication function, even slight decibels changes in consistent measuring can be vividly seen.

• Analog vocal vocalization designed to make a more intuitive feedback in sound noise level learning.

Warning Tips:

1. If doing noise measurement outdoors, please put a windscreen on the microphone head to prevent the microphone from being blown directly to cause airflow noise.
2. Check the instrument carefully before use. If you find any damage or other problems, please do not use and get our support.

Overload Indicator Display

• The meter is perfectly fitted with the common needs of sound noise testing, with the ability to detect decibels range from 30 to 130 dB, and overload indication displaying to make a reminding.

• Whether at home or outdoor, this digital noise meter make it easier to confirm sound levels by standard sounding with data and simulated indication and overload alarming, make the sound be more tangible to enjoy yourself whenever and wherever.

1. When the decibels level is less than 30 dB, “UN” display on the screen
2. When the decibels level is over 130 dB, “OL” display on the screen

LCD Backlit Display & Flashlight

• Keystroke the “ HOLD” button more than 2 seconds to turn on/ off the backlight and flashlight.

• LCD backlight and flashlight are convenient for working in dark environments, for concerning of saving energy, these 2 functions are opened/ closed together and will be automatically off after 1 minute.

Max/Min & Auto Shut Down

• One button switched to change maximum or minimum recorded reading by short pressing the “MAX/MIN” button.

• The meter will be auto off after 10 minutes no activity, and can be closed by keystroking the “SLOW/FAST” and the power button more than 2 seconds at the same time.

Data Hold & Time Weighting

1. With data hold function, you are free to freeze the current measurement reading and easy to record.
2. Time weighting is divided into 2 modes of measuring - slow & fast mode response

• Slow mode - With response time of 1 s, the meter is generally used to measure steady-state noise, and the measured value is a valid value.
• Fast mode - With response time of 125 ms, the meter can measure unsteady noise and traffic noise with large fluctuations. The fast gear is close to the human ear's reaction to the sound.

User questions & answers

Question:	Can this meter show average over time of, say, an hour-long phone conversation
Answer:	stereo 1/4" can be adapted to RCA, it would have to be 4-pole ie: TRRS balanced to go into xlr
Question:	can you set the unit to be always on? As well as the backlit display - can you set that to always on too
Answer:	You need a small pre amp to go into then to this unit
Question:	Will it read over 130 tho
Answer:	It's smooth across the rotation. It does push in to turn it on or off.
Question:	Is triplett sonichek pro 3550 tripod mountable, does it have threaded inset to accept standard (camera) tripod mount
Answer:	I would say that it will probably work. It plugs into your rca cables and has another set of rca out to run to the inputs on the amp.
