b. Adjustments
(1) Set calibrator to STANDBY.
(2) Press TI RANGE 20 pushbutton.
(3) Set calibrator for a 19 V, 200 Hz output. Adjust R303 (fig. 2) for a 19.000 TI
indication (R).
(4) Set calibrator for a 1.9 V, 200 Hz output. Adjust R302 (fig. 2) for a 1.900 TI
indication (R).
(5) Repeat (3) and (4) above for best compromise.
(6) Set calibrator for a 19 V, 10 kHz output. Adjust R102 (fig. 2) for a 19.000 TI
indication (R).
(7) Set calibrator for a 1.9 V, 10 kHz output.
(8) Press TI RANGE 2 pushbutton. Adjust C102 (fig. 2) for a 1.9000 TI indication
(R).
(9) Set calibrator for a 1.9 V, 100 kHz output. Record TI indication.
(10) Press TI RANGE 20 pushbutton.
(11) Set calibrator for a 19 V, 100 kHz output. Adjust C202 (fig. 2) for a TI
indication numerically the same as recorded in (9) above (R).
