After performing this check, set calibrator for a 0.9 V, 1 kHz output and record TI indication (0.0009 V) for use in b(9) below.

After performing this check, set calibrator for a 0.3 V, 1 kHz output and record TI indication (on the 0-to-1 scale) for use in
2
b(15) below.
3After performing this check, set calibrator for a .9 V, 1 kHz output and record TI indication for use in b(l2) below.
(8) Connect TI INPUT to calibrator WIDEBAND output and press calibrator
WBND pushbutton.
(9) Set TI RANGE switch to .001 VOLTS.
(10) Set calibrator for an initial 900 V, 1 kHz, wideband output. Adjust calibrator
for a TI indication equal to value recorded in table 3 (0.0009 V) to establish a 1 kHz
reference. Press calibrator NEW REF pushbutton.
(11) Set calibrator frequency to 20 Hz, then readjust amplitude for TI reference
established in (11) above. Calibrator Error display indication will be < 5.6 percent.
(12) Repeat technique of (12) above for remaining frequencies listed for the .001
VOLTS RANGE switch settings in
table 4. Calibrator Error display will be within
specified limits; if not, perform b (9) through (11) below.
(13) Repeat technique of (10) through (13) above for TI RANGE switch settings and
calibrator initial voltage listed in table 4. Calibrator Error display indication will be
within the limits specified; if not, perform b (12) through (14) below for 1 VOLTS RANGE
switch setting and (15) through (17) for .3 VOLTS RANGE switch setting.
