In the process of using the microcomputer relay protection tester, everyone usually just uses it according to the instruction manual or does not carry out systematic use training when purchasing it. In this way, you will always be at a loss when encountering difficult problems. Let us learn the specific use of the test instrument today!

1. Wiring instructions.

The yellow, green, red, and black terminals on the panel of the microcomputer relay protection tester are the voltage output terminals connected to the instrument. There are DC output and power connections on the back of the panel. There is a grounding jack next to the power jack, which is convenient for the tester to ground the equipment.

After turning on the power of the instrument, turn it on. According to the color of the coil, connect the terminal of the corresponding color. For example, the black coil is inserted into the black jack of the current output of the instrument, and the other end is connected to the relay. In the same way for other colors, do the corresponding wiring operations according to the corresponding parameters and colors. Then use a multimeter to test the wiring to see if the wiring is successful.

Second, the operation demonstration.

Adjust the current amplitude and amplitude step size according to the current phase of the terminal itself. The single-phase test does not need to set the phase, and other phase tests need to adjust the phase, and then set the phase step size. Adjust the test type to your own test type (manual or automatic) to start the test. During the test, when you hear "bell~", turn the button to "stop", and then get the test action time. If you need to increase the test time, you can adjust the amplitude step size.

3. Output detection of AC voltage and AC current.

Finally, remove the test line and use a multimeter to detect the output of current and voltage, return the interface to the parameter setting interface of the AC test, and also set the voltage amplitude, amplitude step size and other parameters first, and then use the multimeter head to test the operation panel. voltage output. Then adjust the current amplitude, amplitude step and other settings, turn the multimeter to the AC gear, plug the multimeter head into the current output of the panel, turn the button on the instrument panel to start the test, and observe whether the multimeter matches the current on the instrument. Agree, complete the test.
