|[AMRadio] Westinghouse Test Meter Unit Type TCT|

I believe the panel you describe is from an Electric Utility Company's
transmission sub-station carrier current test panel.
They frequently transmit carrier current acrossed the high tension lines to
control devices at a remote location and transmit voice and telemetry data.
This is just a simple vom and RF milliamp meter you describe.
It slips into a bracket usually near the top of a 19" rack. You generally
have a couple of these at the site and you can move them from rack to rack
as you test and calibrate the carrier units associated with each power line.
I hope this answers your question. Sorry it's not about some neat piece of
rare radio gear but it is still RF...

Can anyone tell me what this was used for,
and what it is a part of?
Westinghouse Test Meter Unit Type TCT.
Unit measures approx. 17" W x 5" H x 3.25" D,
and is completely enclosed.
It has two 4.5" W x 4" H meters.
The left meter is R.F. Milliamperes, with 4 scales:
0-100, 250, 500, 1000. A 5 position switch,
(RF MA, OFF, 1000, 500, 250, 100), is to the left
of this meter.
The right meter is a VOM (20K ohms/volt DC, 5K ohms/volt AC).
To the right of this meter are two switches:
One is FUNCTION: OFF, DCV/DC MA, ACV, DB, 2.5 DC AMPS, OHMS.
The other is RANGE: 0-2.5 AC, 0-10, 50, 250, 500 V AC/DC;
0-.25, 2.5, 25, 250, 1000 MA; R x1, x10, x100, x1K, x10K;
0 DB, +12 DB, +26 DB, +40 DB, +46 DB.
Between the two meters is an OHMS ADJ control.
Below each meter are 5-way binding post connectors.
On either end of the front panels are curved handles,
in the center of which is a button that when depressed,
allows spring latches on either end on the unit to
retract inside the unit, thus allowing this unit to
be inserted into another unit.
