JYR50C/40C/20C WR tester



1. Test range upto 20K ohm
2. Charging voltage upto 30V, faster charging testing speed.
3. With demagnetizing function for eliminating transformer remanence, avoiding difficulties in closing.
4. With calendar and storage function, no lossing as power off.
5. With inductive load which can protect  from arc.
