主要特点
1) Component Tester
2) 高灵敏度 X-Y 模拟
3) Z axis (intensity modulation)
4) TV VIDEO SYNC Filter 电视信号同步滤波器
5) High frequency rejection filter in the trigger circuit
COMPONENT TESTER is the special circuit with which a single component or
components in or out of actual circuit boardcan be easily tested requiring no
power to drive the circuit.
The display shows FAULTS of components, size of a component value, and
characteristics of components, and half-deadcomponents under a dynamic test.
