Operating Conditions:
◆ Working power supply: 220V ±10% 50Hz
◆ Ambient temperature: -10℃～+50℃
◆ The product should be placed in an environment free from gases, vapors, chemical dust, dirt, or other explosive media that could seriously affect transformer insulation.
Working Principle:
◆ The instrument must be properly grounded.
◆ After connecting the working power supply, turn on the switch, the red indicator light will illuminate. Press the start button, the green indicator light will illuminate. Connect the output terminal to the test object, and the current generator is ready for current rise.
◆ Rotate the voltage regulator evenly clockwise, and pay attention to the output current indicator on the operation panel until the required high current is reached.
◆ During the test, if any abnormal phenomenon is found, immediately cut off the power supply, identify the cause, and then proceed with the test.
◆ After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power supply, and then disconnect the test wiring to ensure safety.
Precautions:
◆ For newly installed transformers or those not used for a long time, measure the insulation resistance between coils and between coils and ground with a 1500 megohmmeter before operation. Only when the resistance value is not lower than 0.5 megohm can it be used.
◆ During use, the current generator transformer and the operation console must be reliably grounded to ensure safety.
◆ When in use, the current should be increased slowly and evenly, and avoid excessive vibration during handling.
◆ The contact surface between the voltage regulator and the brush should be kept clean. If necessary, wipe it clean with cotton yarn dipped in 90% alcohol.
◆ This equipment should be stored indoors in a clean, ventilated, and dry place.
