b. Adjustment. No adjustments can be made.
a. Performance Check
NOTE
This performance check is not applicable for models 5305.
(1) Position TI controls as listed in (a) through (f) below:
RES-VAR-MUR switch to MUR.
(a)
BA switch to EXT.
(b)
Decade dial 1000 to 1.
(c)
Decade dials 100, 10 and 1 to 0.
(d)
(e)
Mechanically zero galvanometer.
Replace mounting screw removed in paragraph 7 d above.
(f)
(3) Adjust both decade resistors to 0 ohms and record TI galvanometer reading as TI
(4) Adjust decade resistor A to 1000 ohms.
(5) Adjust DC power supply for 25 volt dc output as indicated on power supply meter.
(6) Position TI MULTIPLY BY switch and decade dials to settings listed in table 6.
(7) Depress TI GA SENS .01, .l, and 1 in turn while increasing or decreasing
resistance of decade resistor B until TI galvanometer pointer indicates 0. Indications on
decade resistor B will be within limits listed in table 6, minus zero resistance recorded in step
(3) above.
