User questions & answers

Question:	Does it do 120 -180db
Answer:	It's not entirely accurate to say that it will "melt," but not far off. This device has no battery to insert, but the tip is of a different metal from the long sleeve. Likely the sleeve is copper or brass (a copper alloy), and the tip is probably zinc. When placed in moist soil, the two metals form a difference in electrical potential, essentially a battery. The electrical potential will corrode, dissolving the zinc tip over time. The same mechanism is used in ships, rocks, and bridges: they attach replaceable zinc electrodes to the steel, to make the zinc corrode instead of the steel. If you leave this in the soil, the corroding zinc from the tip will be electrodeposited on the sleeve, reducing the electrical potential, and eventually making the current stop flowing. You will then have to rub the zinc off the sleeve to make the meter work again. Over time the zinc tip would disappear. So, the answer is NO, you can't leave it place. You should get a reading, then remove it from the soil and wipe it clean and dry each time. ...and now you know WHY you have to do it.
Question:	Is this unit self calibrating? Does it require any calibration
Answer:	Soil left on the probe has moisture and possible fertilizer mixed in and the instructions warn the probe must be wiped off after using the meter on your plants. Using steel wool will possibly bring back the shine to the probe but there's no way of telling if it's accurate.
Question:	Does it came with a case
Answer:	Please could not put this item into the water. Thanks! Here is some notes for your reference, thanks! -Don't measure liquids especially water, it is only used to test the soil moisture. -Choose a soft soil, forbid to force the metal probe into the hard soil. -Please don't put the probe pen for a long time in the soil (no more than one hour), otherwise it will damage the pen. -Don't use the measuring pen near the magnetic material and away from other metal objects. -Don't hold the metal part of the measuring pen by hand. Fingerprints have grease that reduces the accuracy of their measurements. -Don't try to remove the metal tip of the tester. If the tip becomes loose, tighten it clockwise.
Question:	Frequency response
Answer:	I’m having the same problem. I’ve waited and even measured the next day. I can feel the soil is still wet and it reads dry. I don’t get it.

• 【Min/Max/Data Hold Function】 - Note: This noise meter has been calibrated at the factory. IF you want to calibrate it again after using a period of time, please use the 94 dB standard source. The Sound Level Tester records the minimum and maximum sound decibels around any given time range and freezes the current measurement readings.
• 【Large LCD Display】 - Clear readings and easy to use at night, widely used in factory, transportation, car, baby room and audio system office, sound quality control in home, school and construction site
• 【Precision measurement & over-range measurement warning sign】 - Measurement range: 30-130dBA, accuracy: ±1.5dB, resolution: 0.1dB, there will be a warning sign when the standard exceeds the standard
• 【Convenient & Lightweight】 - This sound pressure level (SPL) meter is lightweight and easy to carry. With a mounting hole for the tripod， which can be placed on the stand and is easier to measure when your hands are busy
• 【Auto/Manual Shutdown】 - It will automatically shut down after 10 minutes when not in use. Note: After using, please press and hold the shutdown button for 2 seconds.

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:	Someone mentioned that the audible alarm lasts for 2 minutes. What if I just want a 5 second notification
Answer:	You can adjust the following 4 things pertaining to the alarm: 1) what decibel level sets it off, 2) when triggered, how long does the alarm go off (defaults to 120 seconds, but you can adjust it down), 3) how loud the alarm should be when it goes off (it beeps kind of like an alarm clock - this controls how loud the beeping is), 4) you can turn the alarm feature on or off
Question:	does it come with calibration certification or can it be sent for calibration
Answer:	I can't remember if it came with cert, and am sure it can be calibrated, you just need someone who can read/understand Chinese. For what I use it for (live music) it keeps everyone on the same page/parameter (100db is the target). Perfect for me.
Question:	Can you adjust what level the alarm begins to sound
Answer:	Yes you can change the sound threshold for the alarm.
Question:	Can you choose to turn off the alarm? I really just want a visual in my classroom and to avoid adding noise to the environment
