d. A DC load draws measured values of 112.3 volts and 6.20 amperes with
maximum possible errors of 0.2 volt and 0.05 ampere.
(1) First, find the power drain by the load (P = IV) and, second,
find the maximum possible error of the power (quantitative and percent).

PROFESSIONAL ATTITUDE.
a. No amount of knowledge and skill will produce a dependable
calibration specialist if he lacks certain personality characteristics,
which are sometimes called attitudes.
Attitude is as hard to define as
discipline. We can describe the results of good attitude or bad attitude,
in terms of job success or failure, but just what caused the success or
failure is sometimes quite abstract.
b. One way to approach this subject is to discuss the difference
between a job and a profession and then say that the professional attitude
is the right attitude for the calibration specialist.
c. Certain things characterize a profession (the medical profession)
from a trade or craft (carpentry) or a job (ditch digging).
(1) Title. A person skilled in a profession carries a professional
title. In some cases, he is addressed by a general title or a title of rank
within this profession.
At any rate, he can claim identification with a
professional area.
He is a doctor or a lawyer, not a medical worker or
legal craftsman.
Similarly, we have the metrologist or calibration
specialist, not just a worker in a measurement laboratory.
