FAQ
- What is the temperature measurement range?
The temperature measurement range is 10–800°C, which allows the system to monitor temperature changes over a wide range of test conditions.
- Can the system automatically generate test curves and reports?
Yes. One of its intelligent functions is automatic generation of test curves and standardized test reports, which reduces manual data processing and makes test documentation easier.
- Can the system record the operating time of the tested device?
Yes. The system can measure the current action time of the tested component and can simultaneously record its specified operating time for comparison and analysis.
- What protection functions does the system have?
The system provides multiple protection functions, including:
- Overcurrent protection
- Overvoltage protection
- Overtemperature protection
These functions help protect both the test equipment and the device under test during high-current testing.
