    For the price the Logic Probe is barely acceptable I comes with silly large car battery clamps The Memory - Latch feature does NOT work as it should Occasionally it works when the status changes from LO to HI Does not work when the status changes from HI to LO

    the latch feature doesnt work but the probe at least detects the wave

    this is a great probe.I use it to test my IC chips when doing technical repairs of IC sockets.

    Great product and price. It did come with large clamps and I changed it to alligator clips.

    Could have got a lemon. Dont know. The pulse light stopped working approximately ten days ago, which was almost two weeks after the return window closed. When it worked, it worked as advertised. But it just didnt keep working. Going with another brand.

    This came just in time to debug a circuit Ive been breadboarding. Worked as expected, in that it detected the expected TTL pulses. The only fault I have with this probe is the attached clamps. They are great for automotive work, but Im working with smaller pieces and breadboards. The solution is simple. I cut off the clamps and attached alligator clips. Probe functions very well, is easy to handle, and (so far as I can tell) accurate. A good deal for the price.

This logic probe is Portable size and Easy to operate.

If you are now looking for a Logic Probe, exactly, just choose it!

INSTRUCTION About 1-8

1. Probe

2. HI  LED (red LED)

3. LO  LED (green LED)

4. TTL/CMOS Switch: It can be set for the logic family of the circuit under test.

5. Yellow LED: If the PULSE/MEM switch is in the “MEM” position and the unit captures a positive or negative pulse,the yellow LED will light and does not turn off until the PULSE/MEM switch is set to the “PULSE” position.

6. PULSE/MEM Switch: (PULSE) Normal operation mode for pulse or level detection. (MEM) pulse capture or memory.

7. Black Alligator Clip: It should be connected to ground or common of the circuit to be tested.

8. Red Alligator Clip: It should be connected to Vcc of the circuit to be tested.

Note:

  • Dont use the unit if it is damaged or operates abnormally.
  • Dont ground youself when you use the unit.
  • To avoid electric shock,dont touch any naked conductor with hand or skin.
  • Do not operate the meter around explosive gas,vapor,or dust.
  • Never exceed the unit’s limits or the ratings specified in the “Electrical Specifications” section.
  • To avoid damage to the unit,do not input more than 40V AC or DC.
  • Before use,verify this unit’s operation by measuring known signals.

Operation Instruction

Operation Instruction

  • Connect the black alligator clip to ground or common of the circuit to be tested,the red alligator clip to Vcc of the circuit.
  • According to the type of logic to be tested,select TTL or CMOS with the TTL/CMOS switch.
  • Note: TTL level is nominal 0 to 5 VDC,and CMOS levels are 0 to 5-15 VDC.
  • For Pulse or Logic level testing,set the PULSE/MEM switch to PULSE position.
  • Touch the probe tip to the circuit point to be tested.The unit will give LED and sound indications indicating the logic level or signals.
  • For more detailed information,see Table in the “Specification” section.
  • Setting the PULSE/MEM switch to MEM position allows the unit to capture a positive or negative pulse,the yellow LED will light and does not turn off until the switch is set to PULSE position.
