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
M
1 07 A
d . The Voltmeter Calibrator should b e deleted
from the table.
Page 5·2. Figure 5·1. Accuracy Test Setup, should be altered
to show the use of the Fluke 5200A ACk Calbrator rather
than the -hp-Model 745A .
Plge 5·4. Figure 5·2. Accuracy and Frequency Response
Test Setup, should be altered to show the use of the
Systron Donner Model M 107 DC Standard rather than
the -hp- Model 740A.
