I set selector switch on inductance but don't know where the red and black wires go. Instructions are in chinese writing. Online instructions tells how to use the meter but does not tell which of the 3 holes the red wire goes in? I have tried all 3 combinations and all 5 switch locations for L nothing is working. Does anyone know where to find instruction for the meter where red & black goes when checking L ?

If you have and Android phone, you can use the phones camera in Google translate to translate Chinese characters it sees. It's not perfect, but it is useful.

I'm guessing that there is a similar tool on Apple phones.

There is a similar app for Apple phones. Google Translate for iOS. It is much faster when the language packs are downloaded instead of interpreted online.

But I'm betting $5 that Gary has an excuse why your solution won't work for him (or he "already tried that and it didn't work").

Measure a choke:
The manual said the wires are in "mA" and "common". That is strange because many meters use "common" and "V,ohm,Hz".
Looks like my VOM has a problem. I used VOM in the past about 4 years ago to check coils I made and got good readings but now the meter says .046h for every thing I check. A few days ago nothing was testing correct that was driving me nuts, now with test leads in correct location it give me readings that are wrong. Even if i short the test leads together it reads .046h. That is why I needed to know where do test leads plug in I could not figure it out trial & error like before. It is 29 degrees F in the workshop I don't think that will cause VOM to read wrong. I brought VOM in the house tested it after it warmed up 1 hour still reads .046h on any coil I test. Only other options on VOM is Hold & AC/DC button & light on/off button it still reads .046h. I used the VOM 6 months ago to make some coils and had good readings. Looks like I need to buy another VOM to test choke coils anyone have suggestions?

My first suggestion is that you should not buy another DMM/VOM but that you should buy a dedicated LCR meter.

I have no direct experience, but my gut feel tells me that there are too many compromises in a DMM which also measures L and C.

That sounds like a good idea, it cost less, the best thing is it comes from CA should be here in 4 days.
