(15) Repeat (3) through (7) above for the TI weight indicated in table 11. The
gravity compensation weight of column 1 of table 11 should replace the weight specified
in (4) above.

(16) Replace the standard 0-600 psi pressure gage with the 0-10,000 psi pressure
gage.
(17) Place eighteen 500 psi weights on the standard and TI (nominal pressure
9,025 psi).
(18) Place 53/64 oz of weight on the TI to compensate for different design gravities.
(19) If the standard is floating, place 27/8 oz of weight from the avoirdupois weight
set (A2) on the standard. If the TI weight table is floating, place 113/16 oz of weight on
the TI weight table. If the table to which weight has been added falls and the other
rises, the TI is within tolerance If the opposite table does not rise, the TI is not within
tolerance.
b. Adjustments. No adjustments can be made.

(Design Gravity
of Standard 980.665 cm/sec2).
a. Performance Check
(1) Install low-range pistons in cylinder housings of TI and deadweight pressure
tester (A4) (standard).
(2) Connect equipment as shown in figure 4 using standard 0-600 psi pressure
gap.
(3) Place one standard and one TI 100-psi weight on their respective weight
tables.
(4) Apply pressure to equipment setup, using handpump while slowly rotating
weights clockwise until one or both units are floating. Monitor nominal pressure using
pressure gage indication. (Nominal pressure is 105 psi).
(5) Balance will be obtained when weights are rotating clockwise on one or both
units with bottom surface of weight table 1/4 inch above either the TI or standard
cylinder housing.
(6) If the standard is floating, place a 1/8 and a 1/32 oz weight from avoirdupois
weight set (A2) on the standard. If the TI weight table is floating, place a 1/16 and a 1/32
oz weight on the TI weight table. If the table to which weight has been added falls and
