User questions & answers

Question:	Who manufactures the meter
Answer:	The name listed on the case, and the meter itself, is "Dr. Meter", and it is titled as "Dr. Meter Digital Illluminanc...B, O-200,000 Lux Luxmeter" model LX1330B. It shows a URL of "http.//www.drmeter.com". It was mfg. in China, but a USA contact is "Dr. Meter, 30075 Ahern Ave., Union City, Cal., 94587, w/ a phone number of #510-477-0249, & Fax as #510-477-0749.
Question:	Can this measure LED grow light
Answer:	Tl;dr is at the bottom because I have a lot of details. It can, but it is not recommended. Lux meters like this are designed to measure the intensity of visible light, which generally assumes you are measuring white light perceived by humans. What matters for plants (so what matters for your grow light) is Photosynthetic Active Radiation, PAR. PAR is a measurement of how many light particles, or photons, pass by a given point. This means that PAR will also get smaller the further you move from the light because it has dispersed more. Because PAR is much more difficult to measure than ambient light, it is much more expensive, generally in the $300-500 range. I would recommend either checking if your grow light has documentation on it's output in PAR, or contacting the manufacturer to ask. If they do not have this information, then follow their guidelines on how far to place the light relative to your plants. Tl;dr: Lux is not a good measurement for LED grow lights. See if you can find information about the light's output measured in PAR. Source: I designed an LED Grow Light and had to do all this research to figure out what to measure for it.
Question:	Yes this a goodlight meter for photographers
Answer:	I would not use it for photography. There are many better meters to use for that purpose. This meter is made for measuring foot candles and such and is useful for comparative light levels. Gossen or other photo meters would do better and be directly viewable with the scales on such a meter.
Question:	I want to measure light pollution from out door lighting. Need accuracy below 1 lux eg (0.1 to 1 lux
Answer:	From the instruction manual:Light-measuring levels ranging from 0.1 lux to 200,000 lux with auto zeroing and corrected for luminous efficiency function (manually calculated for non-standard light sources).Accuracy is described as: +- 3%+10dgt with a repeatability within 2%.ChuckJ

User questions & answers

Question:	Where is the expiration (or Use by) date
Answer:	This cream doesn't have an expiration date, however, there is a shelf life of 2-3 years. -The Olay Team
Question:	How is this product different 7-in-1 effects cream? "night cream by olay total effects anti-aging night firming cream & face moisturizer
Answer:	I believe the retinol is the major difference. I use their 7-in-1 during the day and just got this to try at night.
Question:	Does this work
Answer:	Alright... as far as it "working" that depends on what your looking for. I'm in my 30's with combination skin and a few fine lines. I started using this cream about 2 years ago. I was spending 3x as much on some other cream with about half the amount in it. I noticed right away that the moisture level alone in my skin increased. It definitely softens lines and rejuvenates, so as far as it being a wrinkle cream.. they don't "go away".. but absolutely less noticeable. I use at night and in the morning under makeup. I have noticed that if I don't give it a few minutes to dry before applying makeup it tends to ball up almost like deoderant and lotion react. It doesn't have a noticeable or unpleasant smell once applied and I can totally see using this cream for years to come. This is the one facial item I NEVER run out of as I always order ahead just because I ♡ it so much.
Question:	What's the consistency of this product compared to the reginerist micro sculpting cream
Answer:	Sorry, I've only used the Olay Night Recovery Cream, so I can't compare. The Night Recovery cream is a thick, white, smooth cream. When you dip your finger into the cream, the cream will stay on your fingers - not run off.

User questions & answers

Question:	which setting is for volts, and which is for ac
Answer:	The V with the two lines is DC volts and the line with the squiggly line is AC volts.
Question:	is the continuity test audible
Answer:	Good question. and I can't find an answer it doesn't say but in the picture when it's showing someone testing continuity it shows that it's beeping what it doesn't say that it does beat and we've got two people on here that say it does not and two people that say that it does so good luck I'm looking for one that is audible myself why all multimeters don't have an audible noise when you have continuity I will never know either that or you can have one that has a paper thin needle that jumps and you can't see it and you have to take your eyes off of what you're working on to see if you have continuity and when you move your head you lose contact and it's such a pain in the ass
Question:	Is this unit protected by a fuse? If so, is it replaceable? My last meter was fused but it was soldered. I couldn't easily replace it
Answer:	I had to replace the ammeter fuse (because I forgot to switch the hot (red) test lead from the left side to the middle, before testing my car's battery voltage). That fuse is 10A 600V. I looked around for those & couldn't find them, but found 10A 250V and these worked OK. They're 20 x 5 mm ( .2 x .79") ceramic fast-blow. https://www.amazon.com/gp/product/B07JFDTTMJ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Question:	Can this handle being plugged into a wall socket? Also, can someone give a walkthrough of how to safely test a socket
Answer:	plug the red lead into the meter socket marked COM and the black into the center meter socket. Set the dial to V~ (for AC volts) on the 200 scale (for household current) insert one probe lead into each of the wall socket's vertical slots and move them around a bit inside the outlet slots to make sure you're getting a good connection, if in doubt plug a lamp or something into the socket. If you suspect the outlet socket itself has failed carefully remove the wall plate in order to access the actual wires connected to the outlet to be sure it's either a dead circuit or the outlet itself has failed.

Flash Duration Measurements

Understanding flash duration is the first step in freezing fast-moving subjects. Since all cameras are limited to relatively low sync speeds, stopping motion in a single image is often achieved by leveraging short flash durations with the camera’s max sync speed. A long-held secret of some of the world’s most talented photographers, the key to freezing action consistently is found in being able to measure flash duration. Photographers are now able to do this easily for the first time, demystifying one of photography’s most challenging techniques.

Increased Light Sensitivity

Increased ISO capabilities in today’s cameras have created a need for light meters to increase their ability to measure light in the dimmest of settings. With an additional 3-stops of light sensitivity for incident light, 2-stops of light sensitivity for reflected light (spot), and an ability to capture a reading down to 0.1 lx of Illuminance, accurately metering scenes lit by candlelight or getting the right measurement for long-exposure night photography is now a possibility.

HSS Flash Measurements

The L-858D-U is the first meter of its kind that can measure the stroboscopic pulses fired from strobes when they are used for Hi-Speed Sync. Finally, photographers now have an accurate way of measuring their lights when they want to overpower the sun or achieve a very shallow depth of field through using HSS.

Flash Analyzing Function

The L-858D is especially useful for on-location shooting to lighten shadows or reduce background detail. That's because it measures ambient and flash simultaneously and automatically indicates the percentage of flash in the total exposure. You can easily adjust the ambient flash mix by turning the Jog Wheel. The digital display indicates the camera settings and an analog display shows the relationship between ambient and flash and the total exposure.

User questions & answers

Question:	All i want to know if this detector gq emp-390 will detect 5ghz wifi signal and 5g cell phone
Answer:	Yes it will detect 5GHz signal but not in all modes of operation. If it is the predominant source then the general Radio Frequency RF mode reading will reflect it. If it is a source mixed with others than all sources will be reported together as one value (sum/average over time...unknown. most likely average). It will not detect it in spectrum analyzer, by frequency, and show it's individual power level. Spectrum analyzer will detect 2.4GHz wifi. 5GHz is out of range of spectrum analyzer as is everything greater than 2.5GHz. It might detect presence of 5GHz data packet bytes in digital mode but I don't know for sure, have not tested this.
Question:	Can it tell you how much emf your cell phone emits
Answer:	yes it does, in 3 scales. some readings read a voltage per meter and another is electro-magnetic reading, I searched through alot and after receiving this I found it to be the best affordable technology in its class, and it even automatically identifies the difference between cell phone and power line EMF in digital readable format.
Question:	Will this device analyze a 5 gig wifi signal like it does a 2.4 or
Answer:	Yes, it does analyze 5 Ghz frequencies. If you are asking whether it will analyze 5G as in 5th generation Millimeter Waves, the answer is NO.. 5th Generation 5G will use frequencies between 30Ghz and 300Ghz... You can get one that costs about $40,000... As in, they are not available to the public .
Question:	Is the 5g wifi signal the same as the new 5g cell phone signal? will it measure the new 5g phones? it is confusing: it says: "rf up to 10 ghz
Answer:	The 5G wifi is referring to 5Ghz Wifi, and it is covered by this meter RF band. The 5G cell phone network is referring to 5th Generation cell phone network, it is nothing to do with 5GHz, basically its base band is much higher than 5Ghz

User questions & answers

Question:	Is the unit truly auto-ranging? i see a "range" button on the unit pictured
Answer:	Yes
Question:	What batteries does it use
Answer:	9v battery. It does come with it. You will have to install.
Question:	For a hobbyist, why would I not buy a $20 multimeter vs something
Answer:	Fora hobbyist the really cheap meters are the best because sooner or later one will test something that will ruin the meter. This meter is really an intermediate meter which is above the hobbyist stage but still below the professional stage. An no, buying a Krug doesn't make you a professional.
Question:	Does continuity test produce a beep
Answer:	Yes. Turn dial to diode setting and press FUNC once. Beep is plenty loud. Great meter for the price.
