电子管毫伏计是电子技术中常用仪器之一.为了保证精度,需要定期校正.我们装置了一台毫伏计电压刻度校正设备,它能计量毫伏计的各档满度、线性误差.输出电压分二档:1.直接从面板的各接线柱上输出10-3-1-0.3-0.1-0.03-0.01-0.003-0.001伏电压;2.从公共接线柱上经开关转换能输出1-0.9-0.8-0.7-0.6-0.5-0.4-0.3-0.2-0.1伏电压.各档电压误差均小于±1%,输出频率为1千赫,谐波畸变近似于1%.它除计量毫伏计外,还可作定点的标准电压之用. Tube millivolt meter is one of the instruments commonly used in electronic technology.In order to ensure the accuracy, we need regular correction.We have installed a millivoltmeter voltage scale correction equipment, it can measure millivoltmeter full scale, linearity error. Output Voltage in second gear: 1. Directly output 10-3-1-0.3-0.1-0.03-0.01-0.003-0.001 volt voltage from each terminal of the panel; 2. Output from the common terminal through the switch can output 1- 0.9-0.8-0.7-0.6-0.5-0.4-0.3-0.2-0.1 Volts. Each voltage error are less than ± 1%, the output frequency of 1 kHz, harmonic distortion is approximately 1% In addition, it can also be used for fixed-point standard voltage.
