6. Description of Test Set, Electron Tube TV-2(*)/U
(fig. 1)
a. Test Set, Electron Tube TV-2(*)/U (tube tester) is housed
in a carrying case equipped with a carrying handle, two electrical
clips for connection to the top cap of a tube under test, operating
and spare tubes, fuses, indicating lamps, and miniature tube pin
straighteners. The cover is secured to the case by luggage-type
fasteners. Power cord brackets and a dummy power cord receptacle on the panel are used to secure and store the power cable.
Tube test data is given on a roll chart; the roll chart case is
mounted inside the cover of the tube tester. A condensed summary
of operating instructions also is mounted inside the cover of the
tube tester. The cover is hinged by slip hinges and can be removed
from the case. Two handles attached to the panel permit easy
lifting of the tube tester from the case.
b. All indicating meters, switches, controls, and tube test sockets
are located on the panel of the equipment. The necessary data for
setting and operating the controls to test the various tube types
are contained in the tube test data roll chart (a above). Two
electrical clips (A and B, fig. 3) provide connection to external
caps of tubes as reqired. One end of the power cord is permanently attached to the panel; the other end terminates in a male
plug.
7. Differences in Models
Test Sets, Electron Tube TV-2/U, TV-2A/U, and TV-2B/U
are similar in purpose, operation, and appearance. On some equipments, the FUNCTION switch and the FIL. CONT. SHORT lamp
are marked LEAKAGE VR and SHORT, respectively. Other
external differences among models of the tube tester are shown
below.

OPERATION
Section I. SERVICE UPON RECEIPT OF EQUIPMENT
8. Unpacking
a. Packaging Data. When packed for shipment, the tube tester
is cushioned on all surfaces and placed within a water-resistant
fiberboard box. The fireboard box is sealed with water-resistant
tape and placed within a wooden shipping box. Spare tubes, lamps,
and fuses are placed in their designated positions within the tube
tester (figs. 1 and 8), The technical manuals are packed within a
close-fitting bag fabricated of waterproof wrapping paper. The
bag is securely sealed with waterproof pressure-sensitive tape.
The wooden shipping box is strapped only for intertheater shipment. A typical wooden shipping box and its contents are shown
in figure 2.
(1) The inside dimensions of a wooden shipping box that
contains a tube tester is approximately 19¼ by 18¼ by
10¾ inches.
(2) The outside volume of the tube tester packed in a wooden
shipping box is 2.16 cubic feet, and weighs 60 pounds.
b. Removing Contents.
(1) Cut and fold back the metal straps.
(2) Remove the nails from the top with a nailpuller and
remove the wooden top.
(3) Do not attempt to pry off the top; prying may damage the
equipment.
(4) Remove the fiberboard box and cut through the three
edges of the box and remove the contents.
9. Checking Unpacked Equipment
a. Check the equipment for any loss or damage that might have
occurred during shipment. If the equipment has been damaged or
is incomplete, refer to paragraph 2.
b. If the equipment has been used or reconditioned, see whether
it has been changed by a Modification Work Order (MWO). If
10
Figure 2.
modified, the MWO number will appear on the front panel near the
nomenclature plate.
c. Check the equipment against the packing list. When no
packing list accompanies the equipment, use the table of components (par. 5a) and/or the basic issue items list (app. III) as a
general check.
