9. Ac Voltage
a. Performance Check
(1) Press function V AC and RANGE 1 pushbuttons.
(2) Set calibrator for an output amplitude of 1.0000 V at an output frequency of
1 kHz. If TI does not indicate within limits specified in first row of table 4, perform
corresponding adjustments in table 4.
(3) Repeat technique of (1) and (2) above, for settings and indications listed in
table 4. If TI does not indicate within limits specified, perform corresponding adjustments
in table 4.
