NOTE
It may be necessary to reinstall the shorting bar between TI
and chassis ground terminals below 1 kHz.
(f) MODE switch to MANUAL (Hewlett-Packard Models 333A and 334A).
(3) Adjust calibrator frequency for 5 kHz and amplitude for an indication of 3 on TI
meter 0 to 3 scale.
(4) Set FUNCTION switch to DISTORTION.
(5) Adjust BALANCE controls and calibrator frequency for a null indication on TI
meter (METER RANGE switch may be reduced to obtain best null indication). If
calibrator frequency does not indicate between 4.75 and 5.25 kHz, perform b below.
(6) Set METER RANGE switch to .3 VOLTS and FUNCTION switch to
SET LEVEL.
(7) Repeat (2) through (6) above, using frequencies, control settings, and indications
listed in table 5.
