ZSQ—1B 型气象图传真机,比 ZSQ—1A 型增加了自动对相电路和方便上纸机构,使该机操作更为简便迅速。但该机自动对相电路设计复杂并采用数字逻辑电路,给检修带来一定困难。针对该电路的特点,通过二次实例检修,初步摸索出对该电路检修方法。
ZSQ-1B-type weather fax machine, than the ZSQ-1A-type automatic phase-matching circuit and the convenience of paper institutions, the machine operation easier and faster. However, the aircraft automatic phase circuit design and the use of digital logic circuit complexity, to bring some maintenance difficulties. For the characteristics of the circuit, through the second instance of overhaul, initially explored out of the circuit maintenance methods.
