(4) Connect TI INPUT to calibrator WIDEBAND output and press calibrator
W BND pushbutton.
(5) Set calibrator for an initial 316 V, 1 kHz wideband output. Adjust calibrator
for a TI indication equal to value recorded in table 3 for 316 V (1 kHz) to establish a 1 kHz
reference. Press calibrator NEW REF pushbutton.
(6) Set calibrator frequency to 500 kHz, then readjust amplitude for TI reference
established in (5) above. If calibrator Error display readout does not indicate within 5%,
perform b below.
(7) Repeat technique of (6) above for remaining frequencies listed for the 316.2 V
range in table 4. Calibrator Error display indication will be within the limits specified.
(8) Repeat technique of (5) through (7) above for remaining calibrator initial voltage
b. Adjustments
(1) Set calibrator output for an initial 1.000V, 1 kHz wideband output. Adjust
calibrator for TI indication equal to the value recorded in table 3 for 1.000V, 1 kHz, to
establish a 1 kHz reference. Press calibrator NEW REF pushbutton.
