Connect RED clip to For + terminal and BLACK clip to - terminal of the power source of the circuit under For . The supply voltage should not exceed 18V DC2. for TTL and DTL, set the upper select switch to the side marked &;TIL&;For CMOS, set the upper select switch to the side marked &;CMOS&;, the probe pin to the point to be tested. The LEDs will indicate its logic states:A) ALL LEDs OFF -High impedanceB) RED ON - High State (1)C) Green ON - low State (0)D) Orange ON - Pulse3. For deteching and storing pulse or level transition, set lower select switch to side marked &;PULSE&; first. the probe pin to the poin to be tested. The LEDs will indicate is basic state. Then set the lower select switch to side marked &;MEM&;, The orange 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&;SpecificationsPart Name:Logic TesterMaterial:plasticSize:14cmColor:black whitePackage content1 For * Logic ProbeNote:1.
