NRJS-3 Series dielectric loss tester calibrator is mainly used to calibrate dielectric loss tester. It has been widely used as insulation testing instrument of power equipment. Due to its high stability and high accuracy (absolute value), the calibrator has been widely used. Therefore, it is a very convenient calibration instrument for both laboratory and field operations.
Overview
Product characteristics
(1) It can simulate 30 levels of dielectric loss values for verification and calibration;
(2) Simple operation and efficient work;
(3) The dielectric loss tester calibrator adopts the principle of simulating loss the power consumption of the loss device itself is very small and it can realize the simulation of any dielectric loss value. With the high-performance single-chip microcomputer it can realize infrared remote control switching;
(4) It can also be used for reverse wiring measurement.
