Qj84 digital DC bridge's main features 1, using 9/2LED large digital display, intuitive, clear, high accuracy, good stability and test speed.
2, using a thin plastic housing, small size, light weight, beautiful appearance, easy to carry.
3, wide measurement range: 0-20kΩ, divided into seven ranges, minimum resolution 1μΩ
4. The main resistance element adopts a mature manganese copper wire wound resistance, and the temperature coefficient is small and highly accurate.
5, the standard resistor inside the bridge, without an external standard, you can calibrate the accuracy of the instrument.
Qj84 digital DC bridge users easy to use, do not need to zero, do not have to standard, test quickly is the choice of industrial and mining enterprises, research institutes, universities, measurement departments of various types of DC resistance for precision measurement, ZY2534 digital DC bridge The specifications, each product has three ranges for different user needs, the product does not need to zero, do not need the standard, the test is convenient and fast, the product price is low, the reliability is good is the most economical test equipment, the instrument attached precision The reference resistor ensures the accuracy and long-term stability of the instrument. The ZY2534 is 10 times larger than the current tested by the ZY9734. The other indicators are the same, but there is no need for zero adjustment and no standard. Accuracy: better than the accuracy of the external galvanometer of the same-class DC resistance bridge.
The advantage of the digital DC bridge is simple: As long as the measured resistance is connected to the selected range, the test process is no longer used manually.
Fast: The sampling time is 0.4 seconds, and stable data is usually displayed within seconds.
Eye-catching: using 200mm large digital display, clear, clear at a glance.
Stability: The main reference resistors are wound with precision manganese copper wire. Stability is better than 0.02%.
Reliable: The main components are imported and aged by special selection.
Qj84 digital DC bridge technical indicators 1, temperature: 5 ~ 40 °C
2, relative humidity: 20 to 75%
3, no strong electromagnetic interference and corrosive gas around 4, range, measurement range and resolution 5, the basic error: 20mΩ file Δ = ± (0.1% Rx + 2 words), the remaining file Δ = ± (0.05% Rx + 2 words) The Rx is guaranteed only when the Δ above the measured resistance value is in the environment of 20±5°C and relative humidity of 50 to 70%.
6, additional temperature error: 0.05 Δ°C
7, overload display function: 0000 flashing display.
8, power supply: AC 220V, 50Hz.
9. Overall dimensions: 250(W)*100(High)*290(Deep)
10, weight: about 2kg 
The advantages of digital DC bridges are mainly reflected in those aspects
The qj84 digital DC bridge is as simple, fast, and eye-catching as a digital multimeter. It also maintains the accuracy, stability, and reliability of the Wheatstone bridge. It is suitable for measuring various shunt resistors, wire resistance of wire and cable, switch, relay, connector contact resistance and other low value resistance.
