|
|
| Leak current measurement, an essential part of electrical safety (For Standard- and Regulation-compliant) |
|
- LEAK CURRENT HiTESTER ST5541: A low-cost solution that complies with standards governing general-use electrical devices
- Uninterrupted polarity switching function dramatically reduces cycle time.
- Support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards.
- Touch panel features simple, interactive operation.
- Communications functionality and external I/O support allow automatic testing on production lines.
