Overview

The difference between Jiangsu DC resistance tester and bridge resistance tester is that the bridge adopts a 5-digit LED display, which can directly read resistance measurement data. It is easy to operate, carry, read intuitively, has high measurement accuracy, and good stability. It can also be used to test the contact resistance of switches, connectors, and relays; Metal riveting resistors for cars, ships, and airplanes.

Product Details

The difference between direct current resistance tester and bridge resistance tester in Jiangsu Province

The DC resistance rapid tester (micro ohmmeter) is a high-precision replacement product for DC single and double arm bridges.
The DC resistance rapid tester adopts excellent switching power supply technology and displays measurement results on a dot matrix LCD display.
Overcoming the inconvenience of reading LED display values in sunlight for other similar products, it also has an automatic arc extinguishing function.
The DC resistance test of transformer windings is a test item for transformers after handover, major repairs, and changes to tap changers.
Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive devices using traditional methods such as bridge method and voltage drop method is a time-consuming and labor-intensive task.
In order to change this situation, shorten measurement time and reduce the workload of testers.
DC resistance tester, abbreviated as DC resistance measuring instrument, DC resistance meter, transformer DC resistance tester, DC resistance detector, DC digital bridge, etc.

The difference between direct current resistance tester and bridge resistance tester in Jiangsu Province

The main technical parameters are as follows:

1. Measurement range: 0-200 Ω

2. Small resolution: 1 μ Ω

3. Accuracy: ± (0.05% Rx+0.05% Rm)

4. The main parameters of each range are shown in Table 1:

(Temperature 20 ℃± 0.5 ℃, relative humidity 40% -60%)

range	test current	resolution	measurement range	basic error
20mΩ	1A	1μ Omega	0-20.000 mΩ	±（0.1%Rx+0.15%Rm）
200mΩ	0.5A	1μ Omega	0-200.000mΩ	±（0.05%Rx+0.1%Rm）
2Ω	100mA	10μ Omega	0-2.00000Ω	±（0.05%Rx+0.05%Rm）
20Ω	100mA	100μ Omega	0-20.0000mΩ
200Ω	10mA	1mΩ	0-200.000Ω

Note: The 20m Ω range is a 4-digit display, and the 200m Ω -200 Ω range is a 5-digit display.

5. Power supply: AC220V ± 22V50HZ ± 1.5HZ

6. Dimensions: 383 * 296 * 166mm

7. Weight approximately: 4Kg
