(3) Place the standard and TI 95-psi weights 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 100 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) Place a 1/16 oz weight from the avoirdupois weight set (A2) on the deadweight
tester designed for a gravity of 980.665 cm/sec2.
(7) Place a 1/8, 1/32, and 1/64 oz weight from avoirdupois weight set (A2) on the
weight table that is floating. If this table falls and the other rises, the TI is within
tolerance. If the opposite table does not rise, the TI is not within tolerance.
CAUTION
Bleed pressure from system prior to removal of any weight.
(8) Replace the standard and TI 95-psi weights with one 100-psi weight on each
weight table. Repeat (4) through (7) above-.
(9) Replace the TI 100-psi weight with a different 100 psi weight. (Do not replace
the standard 100-psi weight.) Repeat (4) through (7) above. Repeat this procedure until
each 100-psi weight has been checked.
(10) Replace the standard and TI 100-psi weight with one 20-psi weight on each
weight table. Repeat (4) and (5) above. (Nominal pressure 25 psi).
(11) Place a 1/64 oz weight from the avoirdupois weight set (A2) on the deadweight
tester designed for a gravity of 980565 cm/sec2.
(12) Place a 1/32 and 1/128 oz weight from avoirdupois weight set (A2) on the weight
table that is floating. If this table falls and the other rises, the TI is within tolerance. If
the opposite table does not rise, the TI is not within tolerance.
(13) Replace the TI 20-psi weight with a different 20-psi weight. (Do not replace
the standard weight.) Repeat (4), (5), (11), and (12) above. Repeat this process until each
TI 20-psi weight has been checked.
(14) Place one 20-psi weight and one 5-psi weight on weight table of standard and
TI. Repeat (4), (5), (11) and (12) above, except use a 1/32 oz and 1/64 oz weight in(12)
above.
(15) Replace the TI 5-psi weight with a different 5 psi weight without replacing
the standard weight. Repeat steps (4), (5), (11), and (12) above except use a 1/32 and 1/64
oz weight in (12) above. Repeat this procedure until each 5-psi weight has been checked.
(16) Replace the standard 0-600 psi pressure gage with the 0-5000 psi pressure
gage.
(17) Remove all weights from the standard and TI weight tables. Place the 95-psi
weight and seventeen 100-psi weights on the standard and TI weight tables.
