Probe earth should be placed closely from test point and lead length should be as short as possible * Recommendable to use miniature socket. (Dont use earth lead.) (2) L CMOS also includes probe capacitance. (3) By-pass capacitor (0.01 F to 0.1 F) is placed closely between VCC and GND. (4) Use the current meter whose internal impedance value is small. (5) Power supply Start up time (0 %VCC to 90 %VCC) of power source should be more than 150 s. Impedance of power supply should be as lowest as possible. 2 Page
