Sonde logique Réponse haute fréquence DTL TTL CMOS Pulse Memory Logic Tester LP-1 , Quick and Easy For DTL, TTL and CMOS High Frequescy Response Instant Indication Pulse Memory Function How to use: 1. Connect RED clip to + terminal and BLACK clip to - terminal of the power source of the circuit under test. The supply voltage should not 18V DC 2. For TTL and DTL, set the select switch to the side marked ""TIL"" For CMOS, set the select switch to the side marked ""CMOS"", contact the probe pin to the point to be tested. The will indicate logic states: A. ALL OFF -High impedance B. RED LED ON - High State (1) C. Green LED ON - low State (0) D. Orange LED ON - Pulse 3. For deteching and storing pulse or level transition, set lower select switch to side marked ""PULSE"" first. Contact the probe pin to the poin to be tested. The will indicate is basic state. Then set the lower select switch to side marked """", The orange LED will light when any pulse or level transition is detected. The pulse direction, in comparison with the original basic, state, cabe determined. After use, reset logic probe by setting the lower select switch back to side marked ""PULSE"" Colour: grey Material: plastic Size: 14 x 3cm Package Contents: 1 x Logic Probe Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
