(4) Set UUT FUNCTION SELECTOR
switch to settings listed in table 2-3. Multimeter
indicates with specified limits.
(5) Set UUT FUNCTION SELECTOR
switch to HELIX (10:1) /HELIX (1:1AC).
(6) Reverse banana plugs on multimeter.
(7) Multimeter indicates between 2K ohms
and 4K ohms.
(8) Set UUT FUNCTION SELECTOR
switch to - 6.3V
(9) Connect multimeter to UUT test points
listed in table 2-4, with 2 test leads (1-9) and
2 probes (1-10). Multimeter indicates within
specified limits.
NOTE
Install UUT in sweep oscillator (1-5).
b. Adjustments. No adjustments can be made.
a. Performance Check.
(1) Connect voltmeter (1-2) to UUT DC-
VM jack with cable assembly (1-7).
(2) Connect UUT SCOPE ACVM jack to

(1-8) and cable assembly ( 1-7). Connect cable
assembly (1-7) from connector (1-8) to volt-
meter (1-4).
(3) Turn sweep oscillator (1-5) LINE
switch to STANDBY and allow approximately
1 minute for equipment warmup.
