Features:
- It has multiple protection functions such as back-EMF impact, test line interruption, power failure, and overheating of the power supply. It can reliably protect the back-EMF impact on the instrument and sound the alarm synchronously.
- Intelligent power management technology, the instrument always works in the minimum power state, effectively saving energy and reducing heat.
- The output voltage is high and the measurement range is wide.
- The test current comes from a high-precision high-current constant-current power supply. No need manual adjustment is required, and the test is quick and accurate.
- The four-terminal wiring method effectively eliminates the influence of test line resistance on the test results.
- Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation.
- Perpetual calendar clock and power-off storage, which can store 1000 sets of test data, which can be consulted at any time
- Bluetooth communication, RS232 communication and USB interface for computer communication and U disk data storage.
- Built-in micro printer.
