In many operations will use the circuit resistance tester, and the current function of the resistance tester is also increasing with the increase of the model, but there are also a lot of people to buy the time to buy the functional equipment, so today please intelligent star about the basic function as a resistance tester should have what.

A, the loop resistance tester type many, now and at the time of purchase should pay attention to the basic function of the project, including testing loop in the circuit of L - and L - N and L - PE L circuit short circuit impedance short-circuit current and expected measured quadrupole method can be used, and pay attention to the two levels of large current measurement method is to 42. A, The level 4 test is 280A, which is a basic function.

Two, now the loop resistance tester not only more stable operation, and the test will be more stable, such as when testing the loop impedance to ensure the accuracy of the results and frequency is up to standard, and for the test results can be stored and transmitted to the computer through data lines, etc., In the current computer popularity today, this is the loop resistance tester should have the basic function.

Three, because the technology is mature so the current circuit resistance tester generally has the characteristics of a wide range of measurement, such as the current tester can be measured in 220V and 380V and 230V and 400V voltage environment, it can be said that the vast majority of the power grid environment can meet the measurement needs of the circuit resistance tester, It can also measure AC voltage and calculate expected circuit short circuit.

Four, if it is a little intelligent or a new type of circuit resistance tester can also directly calculate the expected short circuit and short circuit current can also distinguish phase current and line voltage, at the same time to complete the automatic adjustment range. Just mentioned is the current circuit resistance tester should have the function, in fact, just mentioned are more basic functions of the tester, so in the purchase of the time just mentioned belongs to the object to be investigated, and then according to the specific measurement needs to select specific functions.
