Hello everyone, hope all is doing well.
Kindly I have one question. Can we test by lcr dee 5000 onboard the components such as capacitors and inductors?
thanks in advanced to the all

 

What are we talking about? Is there some reason why you think everyone should know what "lcr dee 5000" refers to?

 

Please write as plainly as possible. We are too diverse to assume a meaning for such a term. We are only trying you help.

 

I believe it’s a brand of hand held test meter which can measure inductance, capacitance (at different frequencies) and resistance - hence L, C and R
The answer I believe is mostly no, testing components in circuit is generally not possible as each component is connected to other components which will interfere

 

There are many LCR meters. The cheapo T-7 from china will give approximations of LCR that are pretty close but that's about it and probably within 10-20% accuracy. The more expensive SZBJ BM4070 will give better approximations that are really close in the range of ±1-2%. Then the EXTECH LCR200 will give almost spot on reading less than ±0.5% as well as ESR evaluations at several fixed frequencies as well as Q and θ readings. These are all handheld meters and then there are bench instruments. More info and precision costs more. Just what do you really need? I have all 3 and the one I use most is the TC-7 unless I'm checking capacitors for leakage and need their ESR or need a more exact capacitance or inductance reading to calculate with. To test in circuit, one leg has to be disconnected from the circuit and capacitors MUST be discharged.

 

No, you have to take the components out of the board to test them.

 

Using an LCR meter to test and characterize frequency dependent components has to be done with some care. We would always make dedicated test jigs to test and qualify components. Controlling source and load impedances is essential for frequency dependent components.

Thank you sir for your reply and your explanation it is awesome.
Best regards

Ok, I got it thanks for your reply.

I'm sorry sir, I have to next time.
What I was asking about LCR meter the brand is (dee 5000 ).
next time I will, and sorry again for that.

 

The closest thing I can find is this, listed as DE-5000.

 

I did find the De5000 which is no longer made and superseded by their De6000. Seems very similar to my EXTECH LCR200 but looking at my standard equipment vendor (TEquipment) has been removed from their stock. So not sure as to its quality even with good specs (common with Chinese made products which are often exaggerated). I think if I wanted a precision LCR I would pass it by. I don't use mine for resistance as my handheld meters or bench meters are quite accurate. I use my 5 digit bench meter for capacitance as it will give readings to 00.000nF which puts it into the pF ability with a precision of ±0.5%. I do use the LCR200 for inductance as most handheld and bench DMMs don't do Inductance plus the LCR200 also gives readings @ several frequencies. Plus, as I mentioned, the LCR200 also gives serial and parallel ESR for both inductors and capacitors if you start getting into filter circuits. There are also several other brands equivalent to the EXTECH LCR200 in the same price range. Look at what is available on eBay both new and used. I've found that even my goto TEquipment dealer sells the same items on eBay for less than what they list them for on their website. If all you are interested in is measuring simple Inductance the ~40USD (or less) BM4070 is sold under several brand names and gives good ±1-2%results (depending on which range is used) on both Inductance and Capacitance. Edit:The BM4070 does not do pFs.

 

I have a DE5000: https://www.deree.com.tw/de-5000-lcr-meter.html

It's a great little unit. I can't vouch for the accuracy specs (which are good), but whenever I compare the readings to my HP4263A (which admittedly hasn't been calibrated for a while), they are very close.

exactly. This this my unit.
