OLS-1000 Analog Overlay Learning System




The main objective of this trainer is to teach the student of electronic circuits rather than focusing on the assembly of the components.

Category Analog and Digital Electronics

To assemble and examine experiment is laborious. OLS Series will condition the students to visualize the function of experiment circuit. Electronic theory will be taught straightly out of book accordingly.

Compatible with ETS-5000 &  ETS-7000A Digital-analog Training System:

1. The OLS -1000 Analog Overlay Learning System allows the student
to assemble even the most involved circuit thus leaving enough
time for fruitful experimentation.
2. The OLS-1000 offering electronic template to guide students to
an immediate and rational experiment layout since symbols of
tracing paper are same as those of traditional circuit diagram.
3. The OLS-1000 Analog Overlay Learning System is compatible
with K&H products of IDL-600A Analog Lab and ETS-7000A
Digital-Analog Training System.
4. No add-ons are required. A standardized set of all necessary
components is included. The thorough courseware was designed
by educators with over 20 years practical teaching experience.
However, the experiments are especially stressed on the theory.
The professional manual is referred to the most widely used theory
books. The schematic diagrams component list and procedure
are clearly offered. Each experiment was tested prior to final editing.
5. Moreover, the continuous hands-on exposure ensures the transfer
of practical technical skills in the minimum time.
