Turn the "Output Fine Adjustment" knob on the instrument panel counterclockwise to the end, turn on the power, and preheat for 3-5 minutes;

Frequency selection: according to the required frequency, turn the "frequency range" switch on the panel to the corresponding first gear, and then use the three "frequency adjustment" knobs "*1", "*0.1", "*0 .01" to the desired frequency according to the decimal principle;

Voltage output: sinusoidal voltage is output from the "output" terminal on the panel. Adjust the "output fine-tuning" knob to make the voltmeter indicate a certain value, and at the same time put the "output attenuation" switch to a certain position (the indication of the voltmeter does not change when the "output attenuation" switch is switched), at this time the output voltage amplitude Decrease the selected "Output Attenuation" dB value for the voltage indication value by the corresponding factor.

 

将仪器面板上“输出细调”旋扭逆时针旋到底，接通电源，预热3-5分钟；

频率选择：根据所需的频率，将面板上的“频率范围”开关拨至相应的一档，然后用三个“频率调节”旋扭“*1”，“*0。1”，“*0。01”按照十进制原则调到所需的频率；

电压输出：正弦电压由面板上“输出”接线柱上输出。调节“输出微调”旋扭，可使电压表指示某一数值，同时将“输出衰减”开关置于某档位置上（转换“输出衰减”开关时电压表指示不变），此时输出电压幅度为电压指示值缩小所选“输出衰减”dB值对应的倍数。
