Notice:
Testing Instructions: 1. Only test one chip at a time. Use one of the three test sockets.
2. For static current testing, use the DC voltage meter of the digital multimeter. Test the voltage across 10 ohms, 1=V/10 (ma). For example, V=15MV, static current 1=1.5 ma. (At this time, do not press the red switch on the right side of the diagram).
3. The test end can be connected to an oscilloscope or frequency counter. Adjust the potentiometer to change the test frequency.
