Nida Model 2100

Digital Multimeter



The Nida Model 2100 Logic Probe provides the student with an instrument for detecting, memorizing, and displaying logic levels, pulses, and voltage transients in mixed and single logic family systems. The 2100 detects out-of-tolerance logic signals, open circuit nodes, as well as transient events down to 50ns while providing the student with an instant high-intensity LED readout. Detecting pulses in digital logic circuitry is presented by Computer Assisted Instruction (CAI), as well as the hardcopy text experiments for the Nida training programs.
