China Wholesale Microwave Diffraction Manufacturers – LEEM-23 Multifunctional Bridge Experiment – Labor Detail:

Main technical parameters
1. Bridge arm resistance R1: Configure a set of precision resistances: 10Ω, 100Ω, 1000Ω, 10kΩ, which are converted by short-circuit plug connection, and the resistance accuracy is ±0.1%;
2. Bridge arm resistance R2: Configure a set of resistance boxes: 10×(1000+100+10+1)Ω, the resistance accuracy is: ±0.1%, ±0.2%, ±1%, ±2%;
3. Bridge arm resistance R3: Configure two sets of resistance boxes R3a, R3b, which are internally installed on the same double-layer transfer switch, and the resistance changes simultaneously: 10×(1000+100+10+1+0.1)Ω, resistance
The accuracy is: ±0.1%, ±0.2%, ±1%, ±2%, ±5%;
4. Standard resistance RN: The resistance values ​​are: 10Ω, 1Ω, 0.1Ω, 0.01Ω, and the resistance accuracy points
Other than: ±0.1%, ±0.1%, ±0.2%, ±0.5%, can be connected externally;
5. Built-in resistance to be measured: Rx single: 1kΩ, 0.25W, uncertainty: 0.1%; Rx double: 0.2 ohm, 0.25W, uncertainty: 0.2%. These two resistors can be used to calibrate the bridge or test whether the bridge is working properly.
6. Digital galvanometer: use 4 and a half digital display voltmeter: range is 200mV, 2V. The display accuracy of the digital galvanometer is: (0.1% range ± 2 words). Galvanometer can be connected externally;
7. Multi-function power supply: 0~2V adjustable power supply, 3V, 9V power supply.
8. When the instrument is used as a single-arm bridge, the measuring range: 10Ω~1111.1KΩ, 0.1 level;
9. When the instrument is used as a double-arm electric bridge, the measuring range: 0.01~111.11Ω, 0.2 level;
10. The effective range of the unbalanced bridge is 10Ω~11.111KΩ, and the allowable error is 0.5%;
11. When setting up an unbalanced bridge, the instrument needs to be equipped with a resistance sensor or temperature control device.
12. All kinds of similar electric bridges can be customized.
