Цифровой мост XJW01 0.3% LCR тестер сопротивления индуктивности емкости ESR готовой

  Caution: discharge before capacitance measurement!! Now the following things are not inculded.   Do not measure charged elements when using. Discharge must be measured before capacitance measurement. Inadvertent measurement of charged components causes improper use. It can detect and replace the front-end protection element 1N4148 by itself.

Please do not pick up the earth, nor touch other charged objects!

L 0.05uh--2000h R 0.1 milliohm --20 trillion C 1p--20 micrometer method   Accuracy 0.3%. The device shell cover is DIY  kits as the following photo, and it needs welding assembly! Need some electronic knowledge and practical ability!     

 

 

Description：

 

2018 New version LCR , Aluminum case ， with power supply adaptor. stand !             smaller than old version, and much more portable！

Please note；   Capacitance must bedischarge before testing    HC HP  connect with  red clip ,  LC LP  connect with black clip The AD converter's words: about 1000 words, by over sampling technology, the effective resolution of about4000 words Measurement methods: quasi bridge measurement, measuring principle is similar to the ratio method for measuring resistance.
