1. The instrument is safe and convenient to operate, fully microcomputerized, with a built-in high-performance CPU imported, high reliability. After setting test parameters according to the 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, external voltage regulator. The external voltage booster can raise the voltage up to 2000V/3A, the external current booster can raise 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 graphic interface. After the test is completed, the volt-ampere characteristic curve can be displayed directly. The graphics are clear and beautiful, easy to analyze. A built-in micro printer can print curves and test results at any time.
5. The XSL8007 transformer comprehensive characteristic tester uses a rotary mouse as the input device, which is convenient and simple to operate and has a long service life.
6. The instrument has a built-in Flash memory. Data will not be 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. It can save and print test results and export test data to EXCEL format documents for editing.
8. The instrument power supply supports adaptive power supply of 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, put the new paper roll on the paper shaft, pinch both ends of the paper shaft, put the paper shaft back in place, release your hands, and the paper shaft will snap into the paper shaft holder. Confirm that the paper shaft is firmly installed.
2. Cut the paper head 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 rotates, then push the paper roll with the cut paper head into the paper inlet at the bottom of the print head, and the paper will be fed into the print head by the printer. After a section of paper comes out from the paper outlet, turn off the power, then thread the paper head through the paper outlet of the front cover, and close the printer panel.
