Operation method of DC resistance tester for AC / DC transfo

The DC resistance tester of zc-205a AC / DC transformer of Wuhan Zhizhuo measurement and control adopts the new power technology, which has the characteristics of small volume, light weight and large output current. The whole machine is controlled by single chip microcomputer, which can automatically complete self inspection, data processing, display and other functions, and has automatic discharge and discharge indication functions. The instrument has the advantages of high accuracy and easy operation, which can realize the fast measurement of the direct resistance of the transformer.

 

 

This paper teaches you how to operate the DC resistance tester for AC and DC transformers

 

1. Wiring method of DC resistance tester

 

Connect the tested object with the test terminal of the machine through the special cable, connect firmly, and connect the ground wire at the same time.

 

(1) Single channel direct measurement wiring.

 

The resistance between Ao phases can be measured directly as shown in Figure 1-1.

 

 

Figure 1-1 single channel measurement wiring diagram

 

(2) Three channel direct measurement wiring. See Figure 1-2.

 

The DC resistance tester can directly and simultaneously measure the resistance values of Ao, Bo and Co, as shown in Figure 1-2.

2. Start up interface of DC resistance tester

 

Turn on the power switch of the DC resistance tester, and the screen will display the interface as shown in Figure 1-3. After staying for about 3 seconds, it will automatically skip to enter the main interface of selection and setting as shown in Figure 1-4,

3. Channel selection interface of DC resistance tester

 

The screen displays the interface as shown in Figure 1-4. At this time, the channel of the tested object can be selected through the corresponding “channel” function key. Each time you press the key, the screen will cycle “three” and “single”.

4. Time adjustment of DC resistance tester

 

In the start-up interface, press the “time” function key to enter the adjustment time interface, adjust the completion time, press the “return” key to return to the start-up interface, and the time modification is completed.

 

5. Reading data of DC resistance tester

 

In the start-up interface, press the “access” function key to enter the view record interface, where you can view circularly, store and view up to 80 groups of data, and press the “return” key to return to the start-up interface.
