Brief Introduction
JJDQ-201 automatic insulation dielectric strength tester is designed by our all scientific and technical engineers, its base on the national standard GB507-86 and standard DL-474 4-92DL/T596-1996,they play their own advantages ,with several field tests ,long-term unremitting efforts, meticulous research and development of high accuracy, full digital industrial instrument .
Main characteristics
The instrument is controlled by a large capacity single chip microcomputer,it is stable and reliable.
1. With a wide range watchdog circuit in the instrument to eliminate the system halted.
2.A variety of operation choices, the instrument has two of GB1986、GB2002 national standard methods and customized operations , which can adapt to various choices for the different users.
3. The instrument oil cup is used with special glass mold for one time, prevent the occurrence of oil spills and other interference.
4.The instrument is designed with special high voltage sampling that allows the test value to enter the A/D converter directly, it could avoid the error caused in the analog circuit and make the test result more accurate.
5. The instrument has the functions of over current, overvoltage, short circuit and other protections. It has very strong anti-interference ability and good electromagnetic compatibility.
6.It’s portable and easy to carry,convenient for inside and outside using.
