inductance meter ?

inductance meter ?
so one meter I have cost thousands a long time ago... I think its 4 digits, but its huge and I avoid using it. I have two others one very cheap the other is missing in action; I know the minute I order another one it will jump at out its hiding place

If you planned to buy a new one today for real use, what would you chouse: I value the people on here's choice as very few other hobbies have inductance been so important

Thanks

Just ordered new one - TH2822E. Costs ~400$ but I'm not really happy with the current I have - the measurement on pF range is way off.

BK 880 is rebadged TH2822, but I prefer to buy the original not the clone. https://www.eevblog.com/forum/testge...branded-meter/

TH2822E. do you think its just your one that is bad... or just not good in that range ?

I had a BK878 which was good. Now I have a DER DE-5000 which I like better. It goes up to 100kHz.

I had a BK878 which was good. Now I have a DER DE-5000 which I like better. It goes up to 100kHz.

my lcr meter (cheap L200A) state that:

L Range、C Range - Abt. 500kHz
Hi.L Range - Abt. 500Hz

At what frequency we need to test for example pulse induction coils ~300uH?
Actually, when i measure L and press function button certain frequency will be displayed. Is that SRF of the coil? I’m a bit ashamed but never really cared about that.

[Carl-NC]

I usually test coils at 1kHz but like the 10kHz & 100kHz option to look at linearity over frequency, especially for multifrequency designs. The coil series R over frequency is useful for determining the effectiveness of Litz wire, for example. But just for measuring PI coils, 1kHz is good enough.

This the same one ?

this one is my choice so far ?

DER DE-5000 is good choice. Costs 100$ without VAT, from Japan, was in top 2 to be honest. Decided to go with the Tonghui. Goes up to 100khz. I mainly need it to measure capacitors with high precision and auto LCR will help when doing reverse engineering.

I use a XJW01 LCR Bridge Meter. Not a bad machine but the instructions are terrible.

This the same one ?

Yes,that's what I have.

That one looks good, too.
