26. Equipment Setup
a. Disconnect TI from impedance measuring system.
b. Connect autotransformer to a 115 V ac source and adjust controls for a 115 V output.
c. Connect TI to autotransformer.
d. Press ON/OFF pushbutton to ON and allow at least 15 minutes for equipment to
warm-up and stabilize.
e. Press ON/OFF pushbutton to OFF. After 1 minute adjust TI meter mechanical zero
adjustment as necessary to position pointer on 0 (zero).
27. Generator Output Voltage
a. Performance Check
(1) Press ON/OFF pushbutton to ON and allow at least 5 minutes for equipment to
warm-up and stabilize.
(2) Connect positive terminal of multimeter to TI GENERATOR OUTPUT
terminal 1.
(3) Connect negative terminal of multimeter to TI GENERATOR OUTPUT
terminal 2.
(4) Turn GENERATOR POWER LIMIT control to 1000 MILLIWATTS.
(5) Set GENERATOR RANGE switch to 2 V.
NOTE
Polarity of voltage at terminal 1 corresponds to GENERATOR
OUTPUT switch setting.
(6) Set GENERATOR OUTPUT +/OFF/- switch to + (positive). Multimeter will
indicate within limits specified in table 11.
(7) Set GENERATOR OUTPUT +/OFF/- switch to OFF.
(8) Repeat technique of (4) through (6) above, using settings and indications listed in
b. Adjustments. No adjustments can be made.
