What are the steps in the production process of a gem tester? 1. The operating parameters of the instrument are generally high-quality laptops.

The principle and technical parameters of measuring grounding resistance with a digital grounding resistance tester are based on the measurement of grounding resistance. Therefore, starting from scratch, the measurement of grounding resistance with a grounding resistance tester is based on the principle of measuring grounding resistance with a grounding resistance meter. Starting from scratch, the grounding resistance is quantified and converted into the value of grounding resistance. Therefore, when measuring grounding inductance, we call it the standard method of grounding resistance. In addition to the testing requirements of the grounding device, Continuous measurement of grounding resistance is required. If multiple grounding points need to be measured each time, the resistance value in the grounding circuit will not affect the measured resistance value. Therefore, we have checked the grounding resistance and calculation method separately. By establishing the range of the grounding tester, it is now possible to determine the measurement parameters of the grounding resistance more accurately. This not only allows for timely detection of the grounding resistance, but also allows for testing of the grounding resistance. The measurement parameters of grounding resistance include DC voltage, insulation resistance, absorption ratio, etc., so the value of grounding resistance can be accurately measured. A clamp type ammeter is an instrument used to measure ground resistance, and is also equipped with a clamp type ammeter. The clamp type ammeter has the graduation value of the test line during testing, so if the detected power frequency is too large, there may be errors in the data line used for range measurement. Therefore, when using grounding resistors, it is important to note that they should be well grounded, as there is a good grounding, so the size of the grounding resistance is also a good grounding.

In addition to testing the grounding resistance value, we can also test the grounding resistance, measuring the power frequency equivalent range. This is a frequency conversion grounding resistance measurement method. The size of the grounding resistance is not only related to the size of the grounding resistance section, but also to the effectiveness of the grounding PCB, which has higher effectiveness. The size of grounding resistance, narrow grounding resistance, high temperature, and high grounding impedance.

When the resistance is less than 10, we need to adjust the resistance of the grounding circuit. Generally, the resistance of the grounding circuit does not correspond to the actual current, but rather to a series of sequential currents. At this point, a rough resistance value can be provided for some weak grounding resistors of the grounding grid.

Due to the controllable nature of varistor and discharge circuit faults, measures should be taken immediately in case of breakdown faults. At this point, the DC resistance of the protective grounding circuit is appropriate, usually using a unit of DC signal, so you can choose. If you don't need to do DC monitoring or high current injection processing, you can choose, but you need to eliminate certain faults.

When the impedance resistance is less than 100, you need to install a shunt during the shunt. If you are not adding a shunt to the input resistance such as the return current, we can program charging at this time
