1. The instrument is safe and convenient to operate, fully computerized, with a built-in high-performance CPU imported, high reliability. After setting test parameters based on interface prompts, no manual contact with the tested equipment is required; the instrument automatically completes the test, keeping test personnel away from high-voltage circuits and ensuring their personal safety.
2. Large output capacity: the maximum output voltage for volt-ampere characteristic test is up to 1000V, the maximum output current for ratio test is up to 600A, and the built-in voltage regulator has an output capacity of 5KVA.
3. Optional accessories include external voltage booster, external current booster, and external voltage regulator. The external voltage booster can increase the voltage up to 2000V/3A, the external current booster can increase the current up to 1000A, and the external voltage regulator can output up to 1500V/20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers up to 500KV class 1A.
4. Large 320*240 dot matrix Chinese character graphical interface. After the test is completed, the volt-ampere characteristic curve can be displayed directly. The graph is clear, beautiful, and easy to analyze. A built-in micro printer allows printing of curves and test results at any time.
5. The XSL8007 Transformer Comprehensive Characteristic Tester uses a rotary mouse as the input device, making operation convenient and simple, with a long service life.
6. The instrument has a built-in Flash memory; data is not lost after power-off. After field tests are completed, test results can be viewed and printed indoors.
7. The instrument is equipped with an RS232 communication interface, which can be connected to a computer via a serial cable to achieve communication between the PC and the instrument. Test personnel can control the instrument through the computer to conduct tests or upload test data from the instrument. The PC application provided with the instrument is powerful, beautiful, and easy to operate, allowing saving and printing of test results, and exporting test data to EXCEL format for editing.
8. The instrument power supply supports adaptive AC220V and AC380V.
◆ Common Fault Maintenance
1. After turning on the power switch, the LCD shows nothing.
Solution: Check whether the power input line is properly connected.
2. No voltage or current output during volt-ampere characteristic test.
Solution: Check whether the voltage regulator switch (overcurrent protection) is turned on.
3. Voltage but no current during volt-ampere characteristic test.
Solution: Check whether the test loop wires are properly connected.
4. No current output during ratio test.
Solution: Check whether the primary test wires are properly connected.
5. The voltage regulator switch trips during startup test.
Solution: Check whether the grounding point of the transformer is disconnected.
◆ LCD Contrast Adjustment
1. When the LCD display is too dark or too bright, it can be adjusted via the potentiometer (terminal 4) on the panel.
◆ Replacing Printer Paper
1. First, disconnect the power, open the printer panel, pinch both ends of the telescopic paper shaft, remove the paper roll shaft from the printer, place the new paper roll onto the paper shaft, pinch both ends of the paper shaft, put it back in place, and release; the paper shaft will be secured in the paper shaft holder. Confirm that the paper shaft is firmly installed.
2. Cut the leading edge of the new paper roll into a triangular shape with scissors, turn on the power, press the paper feed button for 3 seconds, the print head will rotate; then push the paper roll with the trimmed leading edge into the paper inlet at the bottom of the print head, and the printer will feed the paper into the head. After a section of paper emerges from the paper outlet, turn off the power, then thread the paper leading edge through the paper outlet on the front cover, and close the printer panel.
