INTRODUCTION

The LP10A and LP25A Logic Probes are logic troubleshooting instruments that give

visual (LED’s) and audio indications (LP25A only) of logic levels and pulses. They
will also capture positive or negative events as short as 30 nanoseconds. The
probe is powered by the circuit under test.
