LESSON 2. MASS MEASUREMENT BALANCES
Mass Measurements
ACCP SUBCOURSE NO. MM 0479
LESSON OBJECTIVE
Upon completion of this
lesson the student should
be able to:
1. Define the three
methods of mass
measurement.
2. Define the three
balances used.
3. Explain the operational
procedure for each balance.
4. Answer all lesson
exercise questions
correctly.
1. General.
a. This lesson is designed to help you increase your knowledge of the balances used at the Army Area Calibration Laboratory.
These balances are used to certify the weights used by the TMDE Support Teams and other users weights.
b. In the following paragraphs we will discuss the construction and operational principles of the bullion balances, the analytical
balance and mass measurements methods.
2. Mass and Its Measurement
a. Mass Measurements. Since weight is the force with which a mass or body is attracted to the center of the earth (the pull of
gravity), mass measurements determine the force W (weight) produced in a gravitational field: W = (M) (G). This force
depends on gravity (G) which varies with latitude and altitude. Known masses whose values are calibrated for specific
