User questions & answers

Question:	Does this product reliably mesure small capacitances (<50pF) and small Inductances (<1uH
Answer:	I would suggest constructing a set of kelvin clips (there are many youtube links about this) for measuring capacitances and inductances this small.
Question:	Does it currently (as of today April 25 2018) come with power adapter too? or may be currently as a gift or something
Answer:	The power adapter is sold separately. I got mine on eBay. Just search DE5000 Adapter and it'll be there.
Question:	What is the lowest inductance range
Answer:	lowest range is 20.000 uH so it will measure down to 0.001 uH at 2.5% 100KHz
Question:	Does it test capacitors in circuit as well as out of circuit like the atlas esr70 does
Answer:	It can, but like any tester, it will be affected by connected components. ESR test is usually pretty reliable in-circuit as it sends 100kHz (or whatever frequency you pick from the selection) and the impedance of a good cap will be low - 1-2 ohms typically so parallel components should not show up. Capacitance may not be, depends as it will measure all capacitance in-circuit across the node (across the capacitor). Large electrolytics may test close enough, small caps probably not. The other tests, Q, leakage, etc are not in-circuit tests.

• Power Supply: The meter can be powered by included Φ5 DC power supply cable and mini USB cable. You can also install 4×AA batteries. Each way makes the meter work. Note: the AA battery is not included.
• Measuring Range: Capacitance 0.01pF-100mF, inductance 0.001uH-100H, frequency 500KHz/500Hz-50KHz.

User questions & answers

Question:	Can this multimeter be used for an Automtive Tech
Answer:	While this multimeter can do plenty of things for automotive. Most serious mechanics get the 87 or 88 series.
Question:	what is the range of the capacitor that can be tested in this model
Answer:	hope this helps. Range/Resolution: 1000 nF / 1 nFRange/Resolution: 10.00 μF / 0.01 μFRange/Resolution: 100.0 μF / 0.1 μFRange/Resolution: 9999 μF / 1 μFRange/Resolution: 100 μF to 1000 μFAccuracy: 1.9% + 2Range/Resolution: > 1000 μFAccuracy: 5% + 20%
Question:	Can this multimeter be used on vehicles for a parasitic load test? I don't want to spend over $400 for the Fluke 88 as it is for personal vehicle use
Answer:	it has been used on motorbikes for sure. It just needs to be in amp mode. If you're doing parasitic load, then you're focused on DC Amps. The 117 has up to 6, while the 88 has up to 10. I don't see a big issue as you're just doing parasitic, not actual use. If anything actually pulls more than 6, you'll blow the internal fuse and have to replace it, but that's about it. Shouldn't be a problem(I've just tested mine on my car and it works).
Question:	What are the differences to pick between the Fluke 117 and the Fluke 115? My intended use would for ham radio and kit-building of electronic kits
Answer:	The 117 adds • VoltAlert™ technology for non-contact voltage detection • AutoVolt automatic ac/dc voltage selection Both are handy but not essential. Be aware of none of these 'electrician' Flukes (115/116/117) read milliamps or microamps -- essential for electronics troubleshooting & design work but unnecessary for electrician tech work. That said, when reading current in amps they do seem to read accurate down to around at least 0.010 amps (10 milliamps) or so.
Question:	is it two prong or three prong? can't see it in the picture
Answer:	It's actually made to be plugged into a grounded wall socket, replacing the 2 3-pronged outlets with its 6 available grounded outlets. It can even replace the outlet cover and be screwed into place. I've got a bunch of these and love them.
Question:	What are the actual dimensions of this unit
Answer:	against the wall, mine is about 4 inches wide, 4 3/4 inches tall, and about 1 3/4 inches deep
Question:	Will this work with half-switched outlets (where one outlet is always live and one is switched), or do all the outlets get power from only one outlet
Answer:	All power for this device comes from the TOP outlet of your receptacle -- so if that is switched then all outlets on this device will be switched (or if your bottom outlet is switched then all outlets on this device will NOT be switched).
Question:	Can this actually completely replace the existing outlet wall plate, or does it only plug in/screw on TOP of the wall plate
Answer:	This can replace the existing wall plate -- that's how I am using it.

Question:	I need to measure down to 2uh, will this meter do that
Answer:	Lowest range on the BM4070 is 200 microhenries, with a resolution of 0.1 uH. However, accuracy degrades substantially at small inductance values. For example, my instrument reads 0.9 uH with zero test inductance (test lead length is 2 x 8 inches). With a 26 inch pair of test leads, this error increases to 2.3 uH. Thus, it's important to determine and subtract out the stray inductance of your test setup before trying to measure anything as small as 2 uH. Also, I have no precisely known inductances at values this small, so cannot say what the instrument calibration accuracy is in this range. If accuracy/precision are important, I'm afraid you're going to have to obtain a (much more expensive) lab-grade instrument, such as an inductance bridge, capable of measuring down to this level.
Question:	For l/c measurement, what frequency do this use? 100hz? 1khz? 10khz? or

Tips for not accurate measurement:

To measure small capacitance, different measurement principles and different measurement frequencies will lead to different measurement results.

The resistance component affects the accuracy, and the measurement results need to be subtracted from the data displayed before the measurement.

When measuring small inductors and capacitors, if the component feet are suitable, it is recommended not to use the test leads. Please just insert component feet directly into two rectangular jacks of LCR Meter to measure.

User questions & answers

Question:	Will this device measure ESR
Answer:	I think Extech uses "ESR" and "SER" for the same measurement. Makes no sense to me either. Btw, I bought the more expensive Extech LCR200 meter and do not recommend it. The ESR, Q, D, readings do not repeat very well at all. I cannot speaker for the 380193, as I had an accident with mine.

User questions & answers

Question:	Can this be used to safely slowly discharge the capacitor of a microwave without any sparks
Answer:	No
Question:	how well does this work on induction loop testing
Answer:	The DM4070 LCR meter is not for induction loop testing. Induction loop equipment is used to transmit signals to receivers by induction. The DM4070 LCR meter is for measuring the inductance of wire coils, chokes, or transformers. The meter could be used to measure the inductance of the transmitter coil but it is not designed to transmit any signal to be measured by a receiving device.As a side note, I have found the meter to be quite accurate in Inductance and Capacitance measurement. It does exhibit erratic readings if the battery is weak. I have calculated the permeability of transformer cores with the inductance measurements and have been very pleased with the results.

User questions & answers

Question:	how to test smd components with the tester
Answer:	As smd components are so small I don't think you could check them with this tester.
Question:	How do i make it read out the esr value when measuring capacitors
Answer:	It should show it automatically. Mine shows the 'capacitance', 'ESR' and 'Vloss'. Mine shows all 3 readings on the same screen. You have to plug component into holes (1 & 2) or (2 & 3) or (1 & 3).
Question:	Can it check jfets
Answer:	My tester is about a year old so I am sure the new ones have a newer software than mine but I dug out a few JFETs from my parts bin and put them to the test and it seems to check them ok.
Question:	What is the software version? I think it appears on the screen as it boots up
Answer:	I am sitting here looking at my unit and it does not show a software version when it is turned on. I got this one about 6 months ago. May be some changes and newer units may show the software version but mine don't.

User questions & answers

Question:	Can this unit test capacitors as small as 5 Volt 15 PF
Answer:	As long as the Capacitor is discharged, yes than you can measure it's value in 15 pf. AK
Question:	can this meter perform a leak test on motor start capacitors
Answer:	No. This meter is for one test only - ESR of a capacitor. It does not perform any other tests.
Question:	Is there a way to confirm it's v2 with sine wave and not v
Answer:	In the description on my order it is listed as V2. On a scope, with the meter open circuit, the test waveform is a rounded square wave. When connected to a 100 ohm resistor, the waveform is more of a triangle wave. When connected to a capacitor, it is somewhere between a triangle and a sine wave.
Question:	Does this come with an instruction or user manual of sorts
Answer:	A small (pocket size) instruction booklet is included. I was not impressed with the MESR100 V2. My opinion of this product, it is a toy tester, the cables are much too short. I was dragging the tester all over the circuit board trying to get readings because of the (WAY TOO SHORT CABLES.) I 1st used it on a sound bar that was not working which has several electrolytic caps. Some had bulging tops, yet the tester indicated every caps was within specs. I also tested some electrolytic caps in a electronic siren (also not working) and the same results. I also tested other non working products, again the same results. ***I highly suggest you save your money and get a well known brand***.Hope this helps you.

Product features

Advantage of V2:

• 1) Change square wave to sine wave 100 KHz, reduce square wave’s high frequency component, and affect the reading passing the test leads and capacitor.
• 2)Higher Resolution up to 0.001 ohm.
• 3)128X64 dot matrix LCD, with larger value display and information
• 4)Embedded 25V capacitor table at LCD, auto display the capacitor is good or bad reference to common 25V electrolytic capacitor.
• 5)New plastic case, curve design for hand carrying. New stand for 60 degree stand on desk.
• 6)Use 2X AA battery, more convenience and longer battery life than 9V battery.
• 7)Support external USB power, using standard micro-USB port.

Features:

• It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C).
• The impedance become small, and we can then measure the true series resistor value.
• Using this theory, we can measure the capacitor is bad/ damaged or good in condition.
• Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test.
• During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.
• Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check.
