Table 5·1. Required Test Equipment should have the
following changes made:
a. The AC Calibrator recommended model
should be a Fluke 5200A and 5215A.
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 M 1 07 A
d.
The Voltmeter Calibrator should be deleted
from the table.
