(3) Connect TI INPUT to calibrator WIDEBAND output and press calibrator
W BND pushbutton.
(4) Set TI RANGE to .001 VOLTS.
(5) Set calibrator for an initial 0.90 mV, 1 kHz wideband output. Adjust calibrator
for a TI indication equal to value recorded in table 3 for .001 VOLTS (1 kHz) to establish a
1 kHz reference. Press calibrator NEW REF pushbutton.
(6) Set calibrator frequency to 10 Hz; then readjust amplitude for the reference
TI meter indication established in (5) above. Calibrator Error display indication will
be < + 5.28%.
(7) Repeat technique of (6) above for remaining calibrator frequencies listed in table
4 (.001 VOLTS RANGE). Calibrator Error display indication will be within the limits
specified.
(8) Repeat technique of (4) through (7) above for TI RANGE and calibrator outputs
listed in table 4. Calibrator Error display indication will be within the limits specified; if
not, perform indicated adjustments.
b. Adjustments. No further adjustments can be made.
