a. Performance Check
(1) Set RANGE/FUNCTION switch to 2 AC VOLTS.
(2) Set calibrator for an output amplitude of 1.8 V at an output frequency of 1 kHz.
If TI does not indicate within limits specified in first row of table 4, perform corresponding
adjustment as listed in table 4.
(3) Repeat technique of (1) and (2) above using TI settings and calibrator outputs
corresponding adjustment as listed in table 4.
