CDFA WEIGHT VERIFICATION EXAM QUESTIONS
AND ANSWERS LATEST UPDATE 2026-2027
What is the most appropriate action for an official to take when finding a price computing scale that is
not at zero load balance? - correct answer-
The scale test should not be performed until the scale is correct at zero load
The apparent displacement, or apparent difference in the height or width of a graduation or other objec
t with respect to a fixed reference, as viewed from different points is defined as? - correct answer-
Parallaxx
What is a the quotient of aHscales nominal capacity divided by the value of the scale division (Cap/e)?
- correct answer-maximum number of scale divisions (N max)
Cap/divisions: Nmax
Using the following formula, normal capacity <CLC x (number of section -
0.5) which load is permissible based on the maximum nominal capacity for a 4 section, Class 3 L vehi
cle scale with a marked CLC (concentrated load capacity) of 40,00 lb? - correct answer-136,000
4section - .5 X 40lbs= 140 = 140,000
Which of the following is not required to be marked on a separable electronic indicating of an
axle load scale that was manufactured in February 1989? - correct answer-
Load Cell verification interval, V min
You are testing a 60,000 x 10lb axle load scale using a certified test load of 15,000lb. What is the rang
e of acceptable scale indications on an increasing load test when maintenance tolerances are applied (pl
us or minus 1 scale division tolerance for every 500 scale division of applied load? - correct answer-
14,970lb to 15,030lb
1division = 30lbs or +-60
You are examining a digital electronic vehicle scale system. Weight values displayed on the indicating
element and recorded on the printed ticket: - correct answer-Must agree exactly
, What are the basic requirements for a commercial scale? - correct answer--
The scale must be type approved
-The scale must be place in service by a registered service agency
-The scale must be continuously maintained in proper operating condition by the user
The sensitivity requirement (SR) applies to: - correct answer-non automatic indicating scales only
Zero load balance should be observed: - correct answer-After each test load is removed from the scale
You are examining a 100,000 lb x 20lb axle load scale. You use 25,000 lb of certified test weights and
test load for the increasing load test. What is the correct amount of weight to be used for conducting a
decreasing load test? - correct answer-12,500 lb
You are conducting a sensitivity test of a 120,000 lb x 20lb full capacity weigh beam with a single bal
ance indicator. What test load should be used to test sensitivity? - correct answer-20 lb (1d)
Animal scale are used to: - correct answer-weigh single heads of livestock
An automatic weighing device requires operator intervention during the weighing process -
correct answer-False
In chapter one of the field reference manual, there are paragraphs in some of the sections which are sh
aded in gray, bordered and numbered. What does this mean? - correct answer-
They are different than, or in addition to, the requirements of NIST Handbook 44
A scale designed for weighing single head of a live stock are considered: - correct answer-
An animal scale
Except for postal scales, all digital indicating scales shall indicate weight vales using which unit of me
asure? - correct answer-Any of these: 1-2-or 5
The following best describes a piece of equipment when it performance or value-
that is, its indications, its recorded representations, etc-
