I learnt some basic instrumentation when i worked on above Instrument,
Mr. Ravi Rao the Manager in Trans Marketing Pvt. Ltd. gave that
opportunity. TMPL as it was known decades back was in Service and Sales
of many Brands like Racal Dana, Genrad, Data I/O and Electronic
Production Machinery.

The one above was also made at TMPL, it is a Psophometer
which was a
true RMS auto-ranging AC dB level meter with weighted filters. The
weighted filter has to resemble the audio response curve of the ear.
With a built in signal generator in dB settings it becomes a
Transmission Measuring Set. This was in the eighties, it is similar to
this Transmission
Measuring Set
from Aplab, this was the only relevant link i got. I also remember that
aplab also had submitted a sample of a bigger unit then. Then some nice
European units also were being evaluated by the buyer.
