The following instructions are keyed to the table of teat data given In paragraph & For comule@ operating inatruetions see TM 11-6625-274-12, Operator's nnd Organizational Manual, Test Sets, ELECTRON Tube TV-7/U, TV-7 A/IJ, TV-7B/U, and TV-7D/U. & Turn the POWER switch to the ON b. Press push button l-LINE ADJ and hold it down. S1 OWIY rotata the LINE AD- JUST control knob untii the pointer of the meter rcata over the LINE TEST mark.

2 This adjustment is not required for all tubes (refer to Notntiom column). c. Locate the type number of the tube to be taatcd (par. 2) under the column heading Tube twe. d. Refer ta the Notatiene column for $pecinl information pertaining to apcciflc typcc of tubcc. 8. Set the lrILAM ENT VOLTAGE owitch et the voltage shown under the heading Fil. /. Set the selector awitehes as indicated under tbe column headed Setectoru in the fol- . Jowfng order: FILAMENT (left), FILAMENT (right). GRID, PLATE, SCREEN. CATHODE, and SUPPRESSOR. g, Set the BIAS dial at the value listed in the Biaa cohunn. h. Set the SIfUNT dial et the value listed under Shunt. If no setting in indicated for this dial, omit this step, and proceed with the next operation. i. Set the FUNCTION SWITCH to the No. 1 position. j. Insert tbe tube ~ be tested in the proper nocket. k. Readjust the line voltage (b above). t. Rotate the FUNCTION SWITCH through SHORTS smaitions 1, 2, S, 4, and 6.

3 If the n=n lamp glows steadily, or under light tapping, a short is indicated and the tube should be discarded, with the exception of tubes w-hich normally ohow #hortx in certain Dositions as indicated under the Notation@ column. Disregard mo- mentary Sash= between switch wnitions. ?dultiseetion tubca must ha tested for shoti for each ecct{on. On all selector 6witch settings in which the CATHODE selector switch and the SUPPRESSOR selector switch are set for a common pin numlrcr (exeept O and 1 ) the FUNCTION switch wilI indicate short on positions 2 and 3. r% AIIow euffjcient time for the tube to warm up and repcet the nhorta tect (1 above). n. Turn the FUNCTION SWITCH to the proper RANGE position as indicated nnder the ri-dumn heeded Ran#e. o. Prccc the pushbutton listed in the Pre8c column. Read the meter as aeon ea iti needle comes to mat and immediately release the pushbutton. This bulletfn uupersrdea TB 1 l-608 S-l/TO 83 AA21-6-1, 9 October 1957, lncladht8.}

Caution: Never hold the pushbutton down longer than necessary to make the reading. Holding the pushbutton down too long may damage the tube. p. If the n((merical value of the meter rerrding is less than thr minimum acceptable value listed under the heading Min ualue, replace the tube. If the tube tests good, continue the test by testing for gas (q below). Note. Tbc meter indication for tube types such as pentagrid converter-s, mixers, thyratrons, and voltage regulators (listed below) is not a true and conclusive mcaslwcmrnt of the tube condition and value. The final deter- mination of the condition of the tube should be made by an o~rational test in cqiiiprncnt known to meet the applicable repair standard. In some cq uipmcnts, it is necessary to substitute a known good tube of the same type to obtain a true indication of the tube's condition.))

5 Do not discard a tube which dots not operate satisfactorily in thceqoiprncnt, if the test set indicates that the tilbc is good. The tube may operate satisfactorily in another circuit.
