(1) DC resistance tester
HDBZ-3/5/10 Transformer DC Resistance Tester
Scope of application
Suitable for fast measurement of DC resistance of various transformers
Performance characteristics
(1) The current can be automatically selected according to the load, which is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers;
(2) The protection function is perfect, which can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable;
(3) The response speed is fast, and the on-load tap switch can be directly switched in the measurement state, and the instrument automatically refreshes the data;
(4) Intelligent power management technology, effectively reducing the internal heating of the instrument;
(5) The instrument comes with a perpetual calendar clock, which can store 1000 sets of test data, which can be consulted at any time;
(6) The instrument is equipped with RS232 and USB interfaces, which can communicate with computers and store in U disk.
