(12) Place one 20-psi weight and one 5-poi weight on weight table of standard and
TI. Repeat (4), (5), and (10) above, except use a 1/32 oz and 1/64 oz weight in (10)above.
(13) Replace the TI 5-psi weight with a different 5-psi weight without replacing
the standard weight. Repeat steps (4), (5) and (10) above. Repeat this process until each
TI
5-psi weight has been checked.
(14) Replace the standard 0-600 psi pressure gage with the 0-5,000 psi pressure
gage.
(15) Remove all weights from the standard and TI pistons. Place the 95-psi weight
and seventeen 100-psi weights on the standard and TI.
(16) Repeat (4) and (5) above.
(17) Place up to, but not more than, 27/8 oz of weight on the weight table that is
floating. If this table falls and the other rises, the TI is within tolerance. If the other
table does not rise, the TI is not within tolerance.
(18) Replace the low-range pistons with high-range pistons in both the TI and
standard.
(19) Place 475-psi weights on the standard and TI weight tables.
(20) Repeat (4) and (5) above .
(21) Place up to, but not more than 5/32 oz of weight on weight table that is
floating. If this table falls and other table rises, the TI is within tolerance. If he other
table does not rise, the TI is not within tolerance.
(22) Replace the 0-5000 psi pressure gage with the 0-10,000 psi pressure gage.
(23) Place one 475-psi weight and fifteen 500-psi weights on the standard and TI
weight tables (8,000 psi nominal pressure).
(24) Repeat (4) and (5) above.
(25) Place up to, but not more than, 29/16 oz of weight on the weight table that is
floating. If this table falls and the other table rises the TI is within tolerance. If the
other table does not rise, the TI is not within tolerance.
b. Adjustments. No adjustments can be made.
14. Mansfield and
Green, Model
10-10525 or Ametek Model R100 Calibration
(Standard and TI having different Design - Gravities).
a. Performance Check
(1) Install low-range pistons in cylinder housing of TI and deadweight pressure
tester (A4) (standard).
(2) Connect equipment as shown in figure 4, using standard 0000 psi pressure
gage (part of A4).
