[Boatanchors] Westinghouse Test Meter Unit Type TCT

[BSugarberg]

Hello,

Can anyone tell me what this was used for,
and what it is a part of?

Westinghouse Test Meter Unit Type TCT.
Style 293B331A09.

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.

Thank you,
