Practical, Fast and Simple
For DTL, TTL and CMOS
High Frequency Response
Direct Indication
Pulse Memory Function

How to use:
1. Connect the RED clip to the + terminal and the BLACK clip to the - terminal of the power source of the circuit under test. The supply voltage should not exceed 18V DC
2. For TTL and DTL, set the upper selector to the side marked \"TTL \"
For CMOS, set the upper selector to the side marked \"CMOS \", contact the probe pin to the point to be tested. The LEDs indicate its logical state:
A. ALL LEDs OFF - High Impedance
B. RED LED ON - High State (1)
C. Green LED ON - Low State (0)
D. Orange LED ON - Pulse
3. To detect and store pulse or level transition, first set the lower selector to the side marked \"PULSE \". Contact the probe pin to the point to be tested. The LEDs indicate its basic state. Then set the lower selector to the side marked \" \". The orange LED will light up when any pulse or level transition is detected. The pulse direction, in comparison with the basic state, can be determined. After use, reset the logic probe by setting the lower selector back to the side marked \"PULSE \"
