CHART ABBREVIATIONS
REMARKS COLUMN Specifies information pertaining to testing of the tube.
F

Meter should indicate short when LEAKAGE switch is in position 1.

No Leak Check

Do not rotate LEAKAGE switch through positions 1, 2, 3, 4 or 5

Leak On

A short circuit will be indicated on meter for the positions of the

LEAKAGE switch following this abbreviation.

Pe

Pentode section of tube is being tested

Tr

Triode section of tube is being tested.

P1 and P2

Tube shall be tested with switch P in both P1 and P2 positions.

G1 and G2

Tube shall be tested with switch G in both G1 and G2 positions.

K1 and K2

Tube shall be tested with switch K in both K1 and K2 positions.

NOTE: Where, the "2" positions of two or more of the K, P or G

switches is called for, it is recommended that they be pulled down
simultaneously. Unless otherwise stated, these switches must be in
the K1, P1 and G1 positions.

Osc

Oscillator section of tube is being tested.

Whole Tube

Specifies that all elements in tube are being tested simultaneously.

Reg

Shows by how many volts a regulator tube can vary on the

"VR TEST VOLTS" scale.

Firing Lim

The range of voltage following this abbreviation indicates the firing

limits of the tube under test.

Plate Cap

Plate clip should be connected to the tube cap.

Grid Cap

Grid clip should be connected to the tube cap.

Thyra

Thyratron.

X1, X2, X3, etc.

(In the REMARKS column) Indicates the factor used to multiply the

Gm scale reading to obtain the actual Gm value.

Emission test.

Specifies that the tube under test is being tested for cathode emission.

Always use the "Rect. & Diodes” switch for tube quality. When an
"R" appears in the signal column, read the rectifiers O. K. scale.
When a "D” appears in the signal column, read the diodes O. K. scale.

Special plate cap.

This specifies that the top cap is either too large or too small,

requiring the use of a jumper. These are rarely used tubes.

ADDITIONAL ABBREVIATIONS THAT APPEAR IN THE SIG COLUMN ARE:
R

Tube is to be tested as a rectifier.

D

Tube is to be tested as a diode.

VR

Voltage Regulator tube.

E

Test procedure for eye tubes is to be used.
