(4) Set for a 1000 V, 1 kHz output and press BOOST to enable TI output. Adjust TI
output adjustment knob for an indication of 1000.000 V (2 digits) on the ac measurement
standard.
(5) Record calibrator Error display indication in table 14. Verify that the result is
within the limits listed, if not perform b(1) below.
(6) Set for a 600 V, 100 kHz output. Adjust TI output adjustment knob for an
indication of 600.000 V (2 digits) on the ac measurement standard.
(7) Record calibrator Error display indication in table 14. Verify that the result is
within the limits listed, if not perform b(2) below.
(8) Repeat technique of (6) and (7) above for the remaining output levels and
