中文DC resistance box
ZX78
PARAMETER
- Dc resistor is a resistance measure with variable resistance value. The switch used in the resistor is sealed, does not require cleaning, has small contact pressure, long life, and small transformer.
1. Widely suitable for factories, schools and scientific research units for measurement and other experimental purposes.
2. For precise adjustment of resistance and known resistance value in direct current circuit.
3. For the whole machine to check the portable DC single-arm bridge and resistance thermometer. Main technical performance: 1, the resistance value of the resistor adjustment range: 0.01~111111.10 accuracy: 0.005% 2, the residual resistance and tolerance of the resistor is: ro = (20±2) mω 3, the accuracy of the stepper disk.
