b. Adjustments. Perform paragraph 14 below.
11. Dc Current
a. Performance Check
(1) Connect calibrator OUTPUT terminals to TI 2A and LO INPUT terminals.
(2) Press TI mA function pushbutton and AUTO range pushbutton.
(3) Set calibrator for an output of 0 mA. TI will indicate 0 (000.04 mA) (open
circuit). If TI fails to indicate within limits specified, perform b below.
(4) Set calibrator for an output of 1.0 A. TI will indicate between 999.56 to 1000.44
mA. If TI fails to indicate within limits specified, perform b below.
b. Adjustments. Perform paragraph 14 below.
12. Ac Current (models AN/GSM-64D and Fluke 8840A/AF w/wo opt05 and 8840A
w/opt09)
a. Performance Check
(1) Connect calibrator OUTPUT terminals to TI 2A and LO INPUT terminals.
(2) Press TI mA
function pushbutton and AUTO range pushbutton.
(3) Set calibrator for an output of 1.0 A at 1 kHz. TI should indicate between
994.00 to 1006.00 mA. If TI fails to indicate within limits specified, perform b below.
(4) Repeat technique of paragraph (3) above for settings and indications listed in
b. Adjustments. Perform paragraph 14 below.
