How to use high voltage nuclear phase device

The use method of high voltage nuclear phase device is as follows

1. Check before use

1. Self-test to distinguish whether the phase instrument is good, the method is as follows:

First insert the test lead into the FRD nuclear phase meter jack, and insert the other end into the 220V AC voltage. At this time, if there are three reactions, it means that it is good.

2. Use a multimeter to check whether the test line is connected.

3. Use a multimeter or shaker to check whether the resistance value of the attenuation component meets Table 3.

The detection of nuclear phase instrument by the above method is normal, and the nuclear phase can be formally established. If you already know that the FRD nuclear phase instrument is normal, you can also use it without detection. If there is no sound or the sound is very low during the test, it means that the battery voltage is insufficient. The battery should be replaced. The watch case can be opened and replaced with a new 9V stacked battery.

2. Detection before nuclear phase

1. Before the official nuclear phase, the nuclear phase detector should be tested in the same power grid system for goodness. There are three reactions in the different functional phases, and no three reactions in the same phase. Only then can the official nuclear phase be formalized.

3. Nuclear phase operation

1. The nuclear phase operation shall be carried out by three persons, and two persons shall operate under one guardianship. It must be operated phase by phase, recorded one by one, and determined whether they are in the same phase according to the "three, three, and no" statement. For nuclear phase operation, the rules and regulations formulated by the unit shall be carefully implemented.

2. Pay special attention to the fact that the human body must not disconnect the nuclear phase instrument and high voltage connection during operation, and the human body and the nuclear phase instrument must be maintained at 2.1m

The safety distance (place the nuclear phase instrument on the upper end of the second connecting rod), the ground wire should be reliably grounded. At the same time, the human body and the high-voltage connection must also maintain a sufficient safety distance (2.1m) (please operate the nuclear phase according to the requirements of the nuclear phaser test operation regulations). The test wire connecting the two test rods is an ordinary 220V wire, and the human body must not release or close the wire at a close distance during the nuclear phase. During use, the long wire should be tied to the root test rod with a cable tie, and at the same time, there must be a sufficient safety distance from the human body (please refer to the high-voltage electrical operation rules), and the high-voltage connection must not contact the ground.
