Ohmic resistance measurement is one of the most important methods of resistance measurement. In many cases, we use this method to measure resistance. The accuracy of the obtained data is more reliable than that of other resistance measurement methods. In fact, when we understand the basic principle of the Ohm meter resistance measurement, we can see that this resistance test is based on the use of the current passing through the galvanometer, although it is not directly proportional to the resistance to be tested, but it has ...

Thin film resistors are used in many applications. In battery devices, the use of thin film resistors is very high, which can effectively improve the battery usage rate, and can also be used to feedback battery data in the battery management system. Usually based on the value of the film resistance, the true conductivity of the material can be calculated by linear fitting, which provides technical support for product development. While testing resistors in batteries, sampling two- and four-probe testing methods are the most c...

The current used by the precision shunt in practical applications does not exceed 80% of the rated current. Although the precision of the precision shunt is small, it can work with a large current. For the voltage of the precision shunt, we use a millivolt voltmeter to measure. However, I need to pay attention to the following points during actual use. In many cases, precision shunts and measuring voltage instruments are used together to directly measure AC and DC currents, calibrate the current functions of various calibrato...

Solar photovoltaics are rapidly developing from power stations to civilian markets, and inverters are important products for these photovoltaics. Generally, inverters are installed in places that are well ventilated and protected from direct sunlight, which is good for heat dissipation. If the inverter has to be installed in a place that is not conducive to heat dissipation due to site restrictions, it is necessary to consider the derating problem of the inverter and improve the service life of the inverter. At present, many ...
