1.Usage 使用方法
Plug the plug of this product in the required supply power, turn on it, the indicator lights, and the nixie tube displays “1” at the same time.将仪器电源插头插入符合要求的电源后，开启电源开关（ON）指示灯亮，同时数码管显示应为1.
Plug one end of one connection cable (accessory) in the plug-in of “RF Output” set in the back plate of this apparatus, and plug the other end in the receiver port of TV antenna, turn the “Frequency Micro-adjustment” Button to needed frequency, it may produces test pattern and sound in the TV set.将连接电缆（附件）一端插入设置在仪器后板的“射频输出”座内，另一端接入电视机天线接收口，调整仪器“频率微调”旋钮至电视所需接收频率，即可在电视机上产生测试图形和声音。
Push the “Image Selection” Key, it may show kinds of images for selecting, and connect the “Video Frequency Output” Signal with TV Set Video Frequency Input Interface or Pre-display Front end in the TV set, then it produces test pattern signal in the TV set, this method is easy to judge that whether the TV Tuner or mid-amplifier is fault or not.按动“图像选择”键，即可产生不同图形变化。将“视频输出”口信号接入电视机视频输入口或接入机内预视放前端，即可在电视机上产生测试图形信号，用此方法可很方便的判断电视机高频头或中放是否有问题。
Plug the cable in the “Audio Frequency Output” Interface, it may take out the audio signal directly transmit it to TV Input Audio Frequency.用电缆线插入“音频输出”口，可直接取出音频信号供电视机输入音频信号用。
Audio Frequency Signal Selection: Push down the Selection Switch, it selects 1000Hz Audio Frequency Signal, as reset it, it selects Electronic Music;音频信号选择：将选择开关按下时为1000Hz音频信号，复位时为电子音乐。
P/N mode selection: Push down the Selection Switch, it is N mode output pattern, as reset it, it is P mode output pattern. P/N制式选择：将选择开关按下时为N制式输出图形，复位时为P制式输出图形。
