Introduction and Operation Video of RK2672E Voltage Tester Instrument

Meric RK2672E series high-power and high current withstand voltage tester details introduction 1. Product overview Meric RK2672E series is a newly developed high-power and high current withstand voltage tester designed to meet the testing needs of the new energy field. It includes two models: - * * RK2672E * *: single AC output, maximum voltage 5000V, maximum current 500mA. - * * RK2672EM * *: AC/DC dual-use, AC output up to 5000V (maximum current 500mA), DC output up to 6000V (maximum current 200mA). 2、 Panel Structure and Function 1 Front panel - * * display area * *: - Three display windows: displaying timing time, leakage current, and output voltage respectively. -Indicator lights: test indicator light (lit when starting), over leakage indicator light (lit when the test fails, accompanied by a buzzer sound and light alarm), power grounding indicator light (lit when the main power is turned on and the display window is closed), high voltage warning light (lit when adjusting high voltage). -* * Operation buttons and adjustment area * *: - Preset adjustment: Used to set the alarm current, the potentiometer needs to be adjusted with a flathead screwdriver, supporting 200mA and 500mA ranges (optional according to standards). -Time adjustment: The "+" and "-" buttons on the left side of the timed display window are used to set the testing time. -Test pre made key: When pressed, it displays the preset current value, and when popped up, it displays the real-time test value. -Start button (green): After connecting the test object, press this button to start the test. -Adjustment panel: Adjust the output voltage by adjusting it after startup. -Reset button: used to turn off the test (the test light goes out, and the voltage needs to be manually adjusted to 0); When the test fails, you need to manually press this button to reset. -Power switch: controls the opening/closing of the display window (when closed, the display window will turn off and the power grounding indicator light will turn on). -Main power switch (air switch): located on the side of the instrument, controls the power supply of the entire machine. two Rear panel - High voltage output interface: labeled "AC5KV, 500mA", connected to the test circuit end. -External control interface: used to connect the white external control line of the external control test rod. -Body nameplate: Indicate basic information of the instrument. -Grounding terminal of the whole machine: It is necessary to connect the ground wire to the earth to ensure reliable grounding of the instrument. -Power input port: Supports 220V, 50/60Hz input. -Fusible fuse: Built in, located next to the power input port. 3、 Operation method 1 Wiring method (two options) - * * Timing test (no external control) * *: Connect the high-voltage output line to the secondary of the tested object, and connect the test circuit end to the primary (such as the primary to secondary test of a high-frequency transformer). -* * Manual testing (external control) * *: Insert the white external control line of the high-voltage rod into the external control interface, and insert the red high-voltage line into the high-voltage output port; Press and hold the high-voltage rod to start the test, release it to close, and the probe directly contacts the secondary of the tested object (with the primary connected to the black wire). 2. Test steps 1 Connect the tested object (choose according to the wiring method) and turn on the main power switch. 2. Parameter setting: Press the "Test Pre made Key" and set the alarm current (select the corresponding range) by adjusting the potentiometer through preset settings. After completion, press the button. -Set the test time using the time adjustment key (e.g. 15 seconds). 3. Start test: Press the green start button and adjust the voltage to the target value (such as 1500V) through the adjustment panel. The test indicator light and high voltage warning light will light up, and the countdown will begin. 4. Test result: - Qualified: Automatically reset after the time is up, and the voltage needs to be manually adjusted to 0. -Unqualified: The over leakage indicator light is on, the buzzer alarms, and the reset button needs to be manually pressed before adjusting the voltage to 0. 5. End: Turn off the power switch and main power. 4、 Safety precautions - Testers must wear insulated gloves and the workplace must be covered with insulation pads. -Before use, be sure to read the precautions and safety tips of the machine and take proper safety precautions. This series of instruments is suitable for high-voltage withstand voltage testing in the field of new energy. It is easy to operate, safe and reliable, and meets the testing needs of high power and high current.
