A = 44.800 +

0.3125 - (-0.250)

A = 44.8000 + 0.0088889 X 0.1875
A = 44.800 + 0.00167 = 44.80167
A = 44.80167 lbs.
(10) Determine difference between TI and nominal value. Difference will not exceed
the tolerance table. If tolerance is exceeded, perform b below (R).
(11) Repeat (1) through (10) above for each weight being calibrated, using tolerance
listed in appropriate tolerance table.
b. Adjustments.
Adjust weight, using appropriate procedure of
paragraph 14 below.
a. Performance Check
NOTE
Balance (A2) is to be used for double substitution method.
(1) Lock dials on balance and zero adjust.
NOTE
A false zero will result if dials are between any two numbers.
Balance (A2) must be arrested before changing 100 g or 1 kg
knobs.
(2) Place standard weight (A5 through A11) (of value corresponding to value of TI)
on balance pan.
NOTE
Several smaller weights may be summed up to make up the
standard.
(3) Dial weights on balance until indication is on scale (IN-RANGE marker is
illuminated). Record indication on worksheet similar to table 10.
(4) Remove standard weight.
(5) Place TI on balance pan and record indication on worksheet.
