DIGITAL TROUBLE SHOOTING TRAINER FSD

The increased usage of digital technology makes digital trouble
shooting all the more important.

The trainer FSD consist of a simplified frequency counter in which
various faults can be introduced in a simple manner.

The unit is delivered with a manual containing complete functional
description. Selected ”faults” can be induced by 16 switches located at the rear of the unit.

The FSD is a four number digital frequecy counter with two frequency ranges: 0–10 kHz and 0–10 MHz in block:
