(10) Determine deference between TI and nominal value. Difference will not exceed
tolerance value listed in appropriate tolerance table. If tolerance is exceeded, perform b
below (R).
(11) Repeat (2) through (10) above for each weight being calibrated, using tolerance
listed in appropriate tolerance table.
a. Performance Check
NOTE
TI is to be checked at cardinal points listed in tables 1 and 2
within TI range. Use table 2 for 500 grams and lower cardinal
points.
(1) Select weight combination (from appropriate weight set (A4 through A10), Class
S or S-1) for each cardinal point of TI listed in tables 1 and 2.
(2) Energize TI and allow sufficient warm-up time.
(3) Zero and calibrate TI as indicated in (a) through (h) below.
(a) Adjust dials until indicator reads 0000.
(b) Turn arrest-release lever fully ccw (released). Pilot light (inside chamber)
will illuminate.
(c) Press ZERO pushbutton momentarily. Digital display will indicate .000-IN-
RANGE.
