[thebug]

I receive today my new 4070l meter(23$ canadians) direct from china...

That is my test....I test the same coil 5 time with each machine.
---------------------------------------------------------------------------------------------------------------

1: Agilent 1733C reading : 6.019MH to 6.020mh make ( 5 diferent test with same coil).

2: deree de-5000 reading : 6.018MH to 6.019mh make ( 5 diferent test with same coil ).

3: China fish8840 with lcd 128664 : 5.98mh ( 5 diferent test with same coil play 5.92mh to 5.98mh).

4: China 4070l t86 : 6.62mh to 6.82mh make ( 5 diferent test with same coil ).


I m very desappointing with my new pourchase the China 4070l .i buy this because i want a second reference machine.The machine is writing is 2.5 % accuracy but is look more like 12% accuracy

I m sorry my english is not very good because i m french..

That fish8840 product is actually a copy of the German AVR TransistorTester. Sort like diy PeakAtlas component tester. Many many features possible. Handy to make, or buy and correct Chinese component savings.
