Máy đo chiều dài và tìm điểm đứt cáp điện lực T-802
Combining the two test methods of low-voltage pulse and pulse current, can test disconnection, low resistance, high resistance, flashover and other faults.
2. Intelligent judgment of fault distance. In the low-voltage pulse mode, it can automatically select the range, judge the fault type, move the cursor to the fault point and display the fault distance.
3. High test accuracy. When the range is less than 1KM, the 2 test accuracy is less than ±1M. When the range is greater than 1KM, the test accuracy is less than 0.5%.
4. Two operation modes of touching and pressing buttons with more flexible operation way.
5. 7-inch large screen LCD, 160°viewing angle, brightness reaches 750cd/m2, which can meet the requirements of sunlight visibility.
6. Rotate the encoder to move the cursor and the operation is more flexible and fast.
7. Waveform storage comparison function. Test data can be stored in or uploaded to the computer through the USB port for viewing.
8. Backlight brightness and automatic shutdown time can be set, to make the battery working time much longer.
1.3 Technical parameters
1. Working mode: low voltage pulse mode and pulse current mode.
2. The maximum distance of low voltage pulse method is 8KM and the maximum distance of pulse current mode is 100KM.
3. Test accuracy: When the test distance is less than 1KM, the test error is not more than ±1M. When the test distance is greater than 1KM, the test error is 3 not more than 0.5%
4. Test dead zone: 2M
5. Maximum sampling frequency 200MHZ 5. Pulse width: 10ns-10μs
6. Automatic impedance balance adjustment
7. Gain adjustment: combination of automatic and manual
