What Is the B/W TV Demonstrator Used For?
In an analogue monochrome receiver the signal is tuned and amplified, sound and picture information are separated, and deflection circuits sweep the CRT’s electron beam across the screen line by line while the video signal sets its brightness. With the circuit diagram in hand, students follow each stage on the PCB, which suits TV-servicing and electronics mechanic courses in ITI and TVET workshops, polytechnic labs and B.Sc. electronics practicals.
For fault-finding practice the instructor sets a fault through the 4 mm sockets; students note the symptom on the screen and trace it with the diagram and a multimeter or oscilloscope. A CRT set works with high voltages, so make changes only through the sockets, with the power off.
What to Specify When Ordering
- Black-and-white or colour — this B/W model, or the Demonstration Coloured Television, listed as the same kind of kit with a colour CRT.
- Quantity — the minimum order is 10 units.
- Test instruments — a multimeter or oscilloscope is a separate item that can go on the same enquiry.
Frequently Asked Questions
How are faults created on this demonstrator?
Through the 4 mm sockets provided for fault creation. The listing does not state how many faults can be set or in which stages, so ask JLab for the fault list with your quotation.
How does it differ from the Demonstration Coloured Television?
The coloured model is listed as the same kind of kit with a colour CRT; this one has a black-and-white picture tube. Choose it for the basics of monochrome receivers, and the colour kit if your syllabus covers colour TV.
Who manufactures this TV demonstrator?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its own works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of electronics demonstration models and scientific instruments, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The demonstrator is assembled at JLab’s own works, not bought from a trader, so ITIs, colleges, dealers and importers buy factory-direct, each unit is visually inspected before dispatch, and repeat orders go straight to the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Brazil in South America, Mexico in North America, Bhutan in South Asia, Morocco in North Africa and Barbados in Central America and the Caribbean. Tender buyers can see the JLab lab tenders page.
