b. Adjustments
(1) Set RANGE switch to 100 MA.
(2) Insert dc current shunt range plugs in .1 AMPERES position.
(3) Adjust dc power supply and decade resistor to obtain an indication of 100 mV on
ac/dc voltmeter.
(4) Adjust A3R26 (fig. 1) to obtain an average indication of 00.00 on TI (R).
(5) Set RANGE switch to 1000 MA.
(6) Insert dc current shunt range plugs in 1 AMPERES position.
(7) Repeat (3) above.
(8) Adjust A3R27 (fig. 1) to obtain an overrange indication of 000.0 on TI (R).
(9) Repeat a(1) through (6) above.
11. Dc Current (AN/GSM-256, AN/GSM-259, and AN/TSM-55)
a. Performance check
(1) Set FUNCTION switch to VOLTS and RANGE switch to 100 MV. If necessary,
adjust front panel ZERO adjust to obtain an indication of 00.00 on TI.
(2) Connect equipment as shown in figure 3, connection A.
