Sims uses those setups mostly to calibrate Zener voltage references, but she also calibrates voltage standard cells.
Sims大多使用那些设备来校準齐纳电压参考,也校準电压标準单元。
500mW, silicon zener diode. Zener voltage 6 V. Test current 20 mA. +-10% standard tolerance.
500毫瓦,硅稳压二极管。齐纳电压6五,测试电流为20毫安。+-10%的标準容差。
W, silicon zener diode. Zener voltage 160 V. Test current 3 mA. +-5% tolerance.
5瓦,硅稳压二极管。齐纳电压160五,测试电流二点三毫安。+-5%的误差。
