3. Performance description
- All the testing items can be enabled or disabled.
- The number of the motor model that can be selected is more than 1000.
- The threshold value of each types of motor can be entered and saved for a long time. For the inductance and resistance, the system has the function of setting, displaying and judging the unbalanced degree.
- Two options are available if NG appears: “continue to test” and “stop the test”. If NG appears when testing the winding resistance, the test can be stopped after testing the three windings.
- The testing results are stored in the data base, together with the barcode information and test result.
- The testing data can be exported via the USB interface.
- User permission setting avoids the parameter change by misoperation.
- Testing software setting and standby interface introduction
