a. Performance Check
(1) Ensure that calibrator OUTPUT HI, LO is connected to TI V Ω and COM inputs.
(2) Set TI function switch to mV~.
(3) Set calibrator for an output of 5 mV at a frequency of 20 Hz, OPR. If TI does not
indicate within limits specified in first row of table 4, perform b below.
(4) Repeat technique of step (3) above for settings and indications listed in table 4.
If TI does not indicate within limits specified in table 4, perform b below.

(5) Set calibrator output to minimum and disconnect equipment.
b. Adjustments. Complete all performance checks in paragraphs 8 through 14,
recording failures, then perform entire alignment procedure in paragraph 17.
a. Performance Check
(1) Connect calibrator OUTPUT HI, LO to TI mA/A and COM inputs.
(2) Set function switch to A~
.
(3) Set calibrator output for 500 A, OPR. If TI does not indicate within limits
specified in first row of table 5, perform b below.
(4) Repeat technique of step (3) above, using settings and indications listed in
table 5. If TI does not indicate within limits specified in table 5, perform b below.
