1 automatic and fast: the use of high-fine stepper motor to control the voltage regulator boost process according to the national standard test parameters fully automatic pressure test. After the test starts the instrument automatically closes and automatically boosts the boosting speed according to the national standard. It reaches the scheduled voltage and starts to count and keeps the test voltage. It automatically depressurizes the timer until the preset time. After zero the power is automatically turned off indicating that the test is over. Display each sample leak Current and display the test result 2 full-featured: full Chinese interface work status display simple and clear operation wide application; with status display with reminder function the user can see the status of the device at a glance; rotate the mouse operation all functions can be rotated by one Mouse setting all digital adjustment abandoned the old potentiometer adjustment mode the field is very convenient to use; button directly set the target Voltage leakage Current pressure time application freely 3 intelligent security protection: with Current over the protection of the Voltage. Accurate and fast protection ensuring the safety of personnel and equipment 4 output Voltage large measurement is convenient and flexible: the device can customize the output of any voltage of 1-30kV the leakage Current threshold can be set arbitrarily 1-20mA the test time can be arbitrarily set 1-10min and the common insulation equipment parameters are in accordance with the national standard. Integrated synthesis module easy and quick to test 5 friendly man-machine interface: white light large screen 320*240 dot matrix Chinese character graphic interface clear and beautiful writing; can be clearly visible under strong light using high-performance rotating mouse easy to operate long life; comes with high-speed micro printer instant print test data
