NOTE
Before applying pow er to the 2 2 1 3 , make the in itia l
control settings. Connect the 2 2 1 3 to an appropriate
pow er source through a variable autotransform er,
adjusted fo r an output o f 115 V. A pply pow er to
both the instrum ent and the test equipm ent and
allow a 20-m inute warm-up p erio d before com
mencing the adjustments and checks

PROCEDURE STEPS
1.
C h e c k /A d ju s t P o w er Supply DC L ev els and
R ipple (R 946 and R 952)
NOTE
Review the information a t the beginning o f the Adjust
m ent Procedure before starting this step.
a.
Remove the High-Voltage shield (see the ‘ High-
Voltage Shield” removal procedure in Section 6) if the
instrument has the Current Limit board (A19). If the
instrument has the Preregulator board (A18), remove the
protective shield on the bottom of the Main board (A10) to
access the test point pads.
J V A R N I N t ^
To avoid electric shock and instrument dam age when
checking either the H ead Room Voltage o r the
Preregulator Output Voltage, use a digital voltmeter
that is isolated from ground, since the Inverter pow er-
supply circuitry common is a t line potential.
b.
Connect the digital voltmeter low lead to common
(TP934). If the instrument has the Current Limit board (A19),
connect the volts lead to TP952. If the instrument has the
Preregulator board (A18), connect the volts lead to TP940.
c.
CHECK— Reading is + 4.2 V to + 4 .4 V for instru
ments having the Current Limit board. Reading is 41 V to
44 V for instruments having the Preregulator board. If the
reading is within these limits, skip to part e.
