- 1. The machine can be controlled via a mobile phone using dedicated software, allowing test results to be saved to the phone for later retrieval.
- 2. Multiple protection functions are provided, including overheat protection, power disconnection protection, and outage protection during testing.
- 3. Intelligent power management technology helps save energy and prevents the machine from overheating.
- 4. High output voltage with a wide measurement range.
- 5. Fast testing. Test current is generated using a high-accuracy constant current source, with no manual current adjustment required.
- 6. Four-terminal (Kelvin) wiring is used to effectively eliminate the influence of test lead resistance on measurement results.
- 7. 7-inch color touch screen (English interface).
- 8. Built-in perpetual calendar clock and power-off data storage. The unit can store 1,000 sets of test data, which can be accessed at any time.
- 9. Bluetooth communication, RS232 communication, and a USB interface are available for computer communication and USB data storage.
- 10. A micro printer for printing test results.
