(2) Release force to obtain a zero indication on indicators.
(3) Repeat (1) and (2) above two more times.
(4) Set INITIAL LOAD switch to 0 and verify that TI indicator indicates 0.
(5) Readjust load cell indicator BRIDGE-ZERO, if necessary, to obtain a reading
of 0 0000.
a. Performance Check
(1) Set TI INITIAL LOAD switch to 0 and adjust WEIGHT dial to 500 pounds.
NOTE
For Roadrunner II models with 15K load cell, do not certify
below 1000 pounds.
(2) Apply force from hydraulic force H frame for null indication on TI balance meter.
If indication on load cell indicator is not between 475 and 525, perform b below.
NOTE
Do not overshoot null condition. If this occurs, remove force
and repeat a (2) above.
(3) Repeat (1) and (2) above for INITIAL LOAD switch and WEIGHT dial settings
listed in table 3. Load cell indicator will indicate within limits specified.

Replace load cell No. 2 with load cell No. 3 and repeat technique of 7 j through l above.
(4) Release force from system and remove TI cell No. 1.
(5) Repeat 7 e, j through l, and 8 a (l) through (3) above for each of the remaining
two TI cells.
