A few electric machinery produce manufacturer to spent big money to purchase testing instrument, unused however need not. The reason was to buy the testing instrument that does not deserve to cover mostly, won't use, bad nobody are repaired wait for a few kinds of circumstances. Wasted the investment of the enterprise, ignored the quality of electric machinery badly also. Can such enterprise produce the electric machinery that gives qualification? Is in nowadays intense market contended for unexpectedly before the good benefit that can you reap? So does electric machinery produce manufacturer how to purchase testing instrument?
　　
The １ , model according to him product, parameter chooses testing instrument of form a complete set, this need consults concerned professional;
　　
2, the testing instrument with choice technology and after service abundant force produces manufacturer, ichthyosaur of manufacturer of production of the testing instrument on the market is mixed now bead, when the choice however cannot carelessness, beautiful big price bought one caboodle scrap iron however;
　　
3, the enterprise should deploy major to detect eligibly personnel;
　　
4, the instrument should time in use process corrective;
　　
5, the testing instrument introduction that company of electric machinery production needs to use is as follows:
　　
Electric machinery dynamometer: Measure the parameter such as power of voltage of electric current of torsion rotate speed
　　
Electric machinery leaves factory integrated testboard: Resistor of compression, insulation, dc, sky carries Idler electricity (power) , v/LIT all over the ground wait for a test
　　
Electric machinery stator is integrated testboard: Compression ＼ circles insulation resistance ＼ turns to a ＼ of resistor of insulation ＼ dc discern wait for a test;
