(5) Set calibrator to 1 k . Set calibrator error control for a calibrator indication
matching TI indication. If calibrator error display does not indicate within 0.017%,
perform b (2) below.
NOTE
Set calibrator to zero ohm and record TI indication. Subtract
recorded indication from indication obtained in (6) below for
final indication on .1 k range.
(6) Set RANGE switch to .1K and calibrator to 100 . Set calibrator error control
for a calibrator indication matching TI indication. If calibrator error display does not
indicate within 0.020%, if necessary, repeat b (2) for an intolerance condition on both ranges.
(7) Set RANGE switch to 10K and calibrator to 10 k . Set calibrator error control
for a calibrator indication matching TI indication. Calibrator error display will indicate
within 0.017% or less.
(8) Set RANGE switch to 100K and calibrator to 100 k . Set calibrator error
control for a calibrator indication matching TI indication. If calibrator error display does
not indicate within 0.017%, perform b (3) below.
(9) Set RANGE switch to 1000K and calibrator to 1000 k . Set calibrator error
control for a calibrator indication matching TI indication. Calibrator error display will
indicate 0.022%.
(10) Set RANGE switch to 10000K and calibrator to 10 M. Set calibrator error
control for a calibrator indication matching TI indication. If calibrator error display does
not indicate within 0.042%, perform b (4) below.
b. Adjustments
(1) Adjust A7R5 OHMS (fig. 1) for an indication of -9700.0 on TI (R).
NOTE
TIs with serial numbers below 1211A00656 may not have
adjustments.
(2) Adjust A7R14 1K (fig. 1) for an indication of the actual value of calibrator
resistance (R).
(3) Adjust A7R16 100K (fig. 1) for an indication of the actual value of calibrator
resistance (R).
(4) Adjust A7R18 10000K (fig. 1) for an indication of the actual value of calibrator
resistance (R).
