Voltage and Current Tester or portable mutual i

the tester is a kind of all-purpose tester for testing volt-ampere characteristics, ratio, polarity, demagnetization, checks for primary current, ACTV and so on. When test, once set the test voltage/current value, the device will automatically step-up/increase current, and display the test result about volt-ampere characteristics curve, ratio and polarity. Data-saving and print also can be operated in this device. It is not only can avoid the work of manual step-up, record and curve-drawing but also can upload test data, save data or print by connecting USB interface and laptop. It is easy to use and efficient and a high-tech product with high cost performance.Main featuresIts terminal blocks are few and connecting method is simple hence it is easy to use for user.Output voltage is 0-2000V and current is 0-15A for volt-ampere characteristics test.The maximum output current for ratio test is 0-600A.Step-up, increasing current, drawing the volt-ampere characteristics curve, and calculating ratio are full automatic. It avoids the work of manual step-up, record and curve-drawing to make it more efficient.Complete-function: to test the volt-ampere characteristics of CT/PT, ratio, polarity, error curve of 5% ,10%, primary current, ACTV and demagnetization.Large screen with Chinese and English liquid crystal display makes it intuitive convenient.It has a micro-rapid printer and can print the curve drawing and test data.It adopts import electro-optic rotary encoder and it is easy to operate.It has a mass storage and can save 1000 piece test data and keep them even the power is off suddenly.USB Communication interfaceSmall in size, light in weight and portable for moving test. 3.
