completion of this check (with TI switch setting remaining on 70),
set calibrator output to 1.000 V (for each frequency). Record indication on
true rms voltmeter. This establishes your reference level for remaining
TI switchl settings.
NOTE
Perform (10) through (13) below for CN-1000/G and Hewlett-
Packard, Model 350D only.
(11) Set TI DB switches to 0.
(12) Adjust calibrator frequency for 1 MHz and amplitude for 3 V indication on true
(13) Set DB switches to settings listed in table 7. True rms voltmeter will indicate
