Feature Highlights: 1. Handy & Quick-Use Design – Compact and easy to handle, this logic probe tester delivers instant readings for DTL, TTL, and CMOS circuits. 2. High-Frequency Response with Pulse Memory – Captures and stores brief pulses or level transitions, so you won’t miss fast signal changes. 3. Clear Visual Indication – LEDs show the logic state at a glance: Red for High (1), Green for Low (0), Orange for Pulse, and all off for High Impedance. 4. Simple Operation – Just connect the clips, set the mode switch, and touch the probe to the test point—no complicated setup required. 5. Wide Compatibility – Works with DTL, TTL, and CMOS logic families, with support for DC supply voltages up to 18V. Product Details: This logic probe tester is designed for quick, reliable digital circuit analysis. It features pulse memory function to catch transient signals, and a straightforward LED display that clearly indicates logic high, low, pulse, or high-impedance states. The probe is switch-selectable for TTL/DTL or CMOS logic levels, and includes a pulse detection mode to store and show short pulses or edges. No external power is needed—it runs directly from the circuit under test. Ideal for troubleshooting, testing, and prototyping digital circuits.
