Test and Measuring Instruments
OMEGA TYPE LTB – 875 The
Digital Electronic Trainer is intended for elementary as well as
advance training of digital electronics. The trainer cover regular
digital circuits by solder less inter connections through use of 2 mm
brass terminations and patch cords. Various clock generators, logic
level input / output indicators and DC regulated power supply are in
built. The unit housed in sunmica finished wooden box enclosure with
provision for safe keeping of mains cord, patch cords and top lid for
protection during storage.
The Trainer Cover the following experiments

Unique solder - less large size, spring loaded breadboard consisting of
one Terminal Strips with 640 tie points each and 2 Distribution Strips
with 100 tie points each, totaling to 840 tie points. (size:55mm X
170mm approx ).
- DC Power Supply: 5 V ± 0.25V / 500 mA ( IC based regulated output ).
