5-9. PERFORMANCE CHECKS.
a. Connect an AC Voltmeter to 4342A LO
and GND terminals as shown in Figure
S-10. The Performance Checks compare the
4342A instrument with its specifications.
These checks are used in incoming inspection,
periodic maintenance, and after a repair.
Before beginning the Performance Checks, do
mechanical and electrical meter zero adjust-
ments using the procedure in Figure 3-6.
5-11. FREQUENCY ACCURACY CHECK.
An electronic frequency counter is required
for this check.
5-1. Connect Digital Voltmeter to AC
Voltmeter dc output terminals.
