(43) Adjust calibrator for 2 V ac output. Adjust 3V MID (fig. 1) for a meter indication
between 1.85 and 2.15 V ac (ideal 2) (R).
(44) Adjust calibrator for 1 V ac output. Adjust 3V LO (fig. 1) for a meter indication
between 0.850 and 1.15 V ac (ideal 1) (R).
(45) Repeat (42) through (44) above until no further adjustments are required.
(46) Disconnect TI RF probe from calibrator.
