General :
SAT-21A Digital Insulation Tester is portable hand-held tester with battery powered, which is
used for testing the security of power supply instrument. It is with simple and clear operation. It
adopts standard test wire, and could carry out test quickly and store test result.
The design and production of this instrument is based on abundant knowledge and
experiences of electric equipment testing instrument of several years.
Functions :
- Insulation resistance measurement
- Continuity measurement by 200mA test current according to EN61557 standards
- Continuity measurement by 7mA test current ( continuous measurement)
- AC/ DC voltage and frequency measurement.
Features :
- Broad-range insulation resistance to test voltage ( 50^ 1000V DC)
- Tested object could be automatically perform discharge after completing measurement
- Polarity shift of automatic voltage testing in â continuity ± 200mAâ function
- Used for continuity 7mA function of inductive tested object
- Data Memory
- LCD could display the result easy for reading. The operation is simple and clear.
