TEST WAVEFORM AND VOLTAGE SETUPS
WAVEFORM MEASUREMENTS
On the left-hand pages preceding the schematic
diagrams are test waveform illustrations that are in-
tended to aid in troubleshooting the instrument. To test
the instrument for these waveforms, make the initial con-

Changes to the control settings for specific wave-
forms are noted at the beginning of each set of wave-
forms. lnput signals and hookups required are also indi-
cated, if needed, for each set of waveforms.
DC VOLTAGE MEASUREMENTS
Typical voltage measurements, located on the schemat-
ic diagram, were obtained with the instrument operating
under the conditions specified in the Waveforms Mea-
surements setup. Control-setting changes required for
specific voltages are indicated on each waveforms
page. Measurements are referenced to chassis ground
with the exception of the preregulator and inverter volt-
ages on Diagram 9. 'These voltages are referenced as in-
dicated on the schematic diagram.
RECOMMENDED 'TEST EQUIPTMENT
Test equipment in Table
4-1
in the "Performance
Check Procedure", Section
4,
of this manual, meets the
required specifications for testing this instrument.
