(10) Adjust DETECTOR ZERO control, if necessary, for a 0 (zero) indication on TI
meter.
(11) Adjust calibrator controls for a 3 V (microvolt) indication on TI meter.
If
calibrator does not indicate within limits specified in table 12, perform b (2) below.
(12) Adjust calibrator controls for minimum output.
(13) Repeat technique of (9) through (12) above, using settings and indications listed
in table 12. If calibrator indications are not within limits specified, perform appropriate
b. Adjustments
(1) Adjust A1R14 1V ZERO (fig. 5) for a 0 (zero) indication on TI meter.
V
(2) Adjust calibrator controls for a 0.003000 V output and adjust A1R41 3
(fig. 5) for a 3 V indication on TI meter (R).

1When
DETECTOR RANGE switch is set to 3 MILLIVOLTS or greater, connect calibrator OUTPUT terminals to TI DET
INPUT terminals 1 and 2.
2Reverse leads to check neg detection on this position only.
