3. Purpose and Use

Test Set, Electron Tube TV2(*)/U (fig. 1) is a portable tube

t e s t e r of the dynamic mutual conductance type. It is used to test

and to measure performance capabilities and to determine rejec-

t i o n limit for electron tubes used in receivers, low-powered trans-

mitters, and other electronic equipment. The following tests can

b e made with the tube tester.

a. S h o r t t e s t .

b. I n t e r e l e m e n t l e a k a g e t e s t .

c. F i l a m e n t c o n t i n u i t y t e s t .

d. Dynamic mutual conductance test for amplifier tubes.

e. Gas test for amplifier tubes.

f. Emission test for vacuum rectifier tubes.

g. Test of gas rectifier tubes.

h. Test of voltage regulator tubes.

i. Plate current tests for triodes.

j. T e s t o f t h y r a t r o n t u b e s .

k. Electron-ray indicator test for electronic indicator tubes.

l. Ballast

tube

test.
