(29) Reverse lead connections at dc voltage divider input terminals. TI will
remain within tolerance with a negative indication.
(30) Set dc voltage divider dials to .999999TEN. TI will have a negative indication
within 10.3 ppm of dc reference standard 10 V output test report value.
(31) Set calibrator to STANDBY; remove dc voltage divider from equipment
setup, connecting calibrator directly to TI.
(32) Set calibrator to OPERATE. TI will indicate within 10.3 ppm of dc
reference standard 10 V output test report value.
(33) Press FUNCTION/RANGE Range ⇑ key to 100 V range.
(34) Set calibrator output to value recorded as 100 V reference in (15) above. TI
will indicate within 12.4 ppm of 10 times dc reference standard 10 V output test report
value.
(35) Press FUNCTION/RANGE Range ⇑ key to 1000 V range.
(36) Set calibrator output to value recorded as 1000 V reference in (19) above. TI
will indicate within 22.2 ppm of 100 times dc reference standard, 10 V output test
report value.
