(4) Separate DCA OHMS and COM leads.
(5) Repeat (2) through (4) above until no further adjustments are necessary.
(6) Connect DCA OHMS and COM leads to resistance standard No. 1.
(7) Set RANGE switch to RX10.
(8) Adjust resistance standard for 1
indication on TI. Resistance standard will
indicate between 9.5 and 10.5 .
(9) Repeat technique of (7) and (8) above using settings listed in table 8. Resistance
standard indications will be within limits specified.
