Logic Level Tester Module - 5V 3.3V TTL

The logic tester can detect high (1), low (0) logical levels as well as high impedance. The state analyzer is designed to measure waveforms in TTL circuits. It allows for quick examination of the logic level practically anywhere on the printed circuit board of the electronic circuit. The readout of the tester results is displayed by means of LED diodes: blue LED on - HI high impedance 0.6-2.4V or disconnected red LED diode on - H high level (1) above 2.4 V green LED lit - L low level (0) 0.6 V Technical data overall length: 102 mm width: 15mm supply voltage: 3.3V 5V
