18. Resistance
a. Performance Check
(1) Set FUNCTION switch to OHMS and RANGE switch to RX10M.
(2) Adjust OHMS ADJ (rear of TI) for ∞ meter indication.
(3) Connect DCA OHMS and COM leads together and adjust ZERO ADJ (rear
of TI) for 0 meter indication.
(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 1Ω indication on TI. Resistance standard will
indicate between 9.5Ω and 10.5Ω.
(9) Repeat technique of (7) and (8) above using settings listed in table 8.
Resistance standard indications will be within limits specified.

a. Performance Check
(1) Set FUNCTION switch to +DCA and RANGE switch to 150 MA.
(2) Connect DCA OHMS and COM leads to calibrator OUTPUT HI and LO.
(3) Adjust calibrator for a full scale indication on TI. Calibrator will indicate
within limits specified in table 9.
(4) Repeat technique of (3) above using settings and indications listed in table 9.
