(5) Press TI OFFSET pushbutton to ON. TI will indicate 0 (00.004 V dc); if not,
perform b below.
(6) Repeat technique of (4) above for 2, 20, 200, and 2000 range pushbuttons. TI
will indicate 0 ( 3 counts); if not, perform b below.
(7) Remove short from TI and connect INPUT terminals to calibrator
OUTPUT terminals.
(8) Press TI 200 /mV range pushbutton and set calibrator for an output of 100 mV.
TI will indicate between 99.989 to 100.011 mV; if not, perform b below.
(9) Repeat technique of (8) above for settings and indications listed in table 3.
(10) Reduce calibrator output to minimum.

9. Ac Volts (Models AN/GSM-64D and Fluke 8840A/AF w/wo opt05 and 8840A
w/opt09)
a. Performance Check
CAUTION
To avoid instrument damage when calibrating AN/GSM-64 or
model 8840A/AF maximum input is 1000 V rms or 2x107 Volt-
Hertz product (whichever is less), for model 8840A w/opt09 do
not apply input potentials greater than 700 V rms or 2x107
Volt-Hertz product (whichever is less).
(1) Connect TI INPUT terminals to calibrator OUTPUT terminals.
(2) Press TI V AC function pushbutton.
(3) Set TI range and calibrator OUTPUT as specified in table 4. If TI fails to
indicate within limits specified, perform b below.
(4) Reduce calibrator output to minimum.
