Tlble5·1. Required Test Equipment should have the follow­
ing changes made:
a. The AC Calibrator recommended model
should be a Fluke 5200A and 521 SA .
b. The AC/DC Voltmeter recommended model
should be an -hp- Model 3466.
c. The DC Standard recommended model
should be a Systron Donner Model
d . The Voltmeter Calibrator should b e deleted
from the table.
