(e) NUMERIC/USER 100 then Enter.
(f) MENU Trig.
(g) FUNCTION/RANGE Menu Scroll ⇓ until TRIG SGL is displayed.
(h) NUMERIC/USER Enter.
(4) Press FUNCTION/RANGE Range ⇑ or ⇓ key to 100 A range and wait 5
minutes to allow range relays to thermally stabilize.
(5) Press MENU Trig key then NUMERIC/USER Enter key. TI will indicate
between -000.00095 and +000.00095 A.
(6) Repeat technique of (4) and (5) above using range settings and indications
listed in table 5.

(7) Press TI keys as listed in (a) through (c) below:
(a) MENU Trig.
(b) FUNCTION/RANGE Menu Scroll ⇓ until TRIG AUTO is displayed.
(c) NUMERIC/USER Enter.
(8) Perform paragraphs 13 through 17 below on multimeter (not TI) to establish
manufacturer's 24 hour accuracy.
(9) Connect equipment as shown in figure 3.
(10) Set multimeter to measure dc voltage on 1 V range.
(11) Press TI FUNCTION/RANGE Range ⇑ or ⇓ key to 100 A range.
(12) Set calibrator for a 100 A dc output, then using output adjustment controls,
adjust calibrator output for a 100.00000 (20 digits) TI indication.
(13) Divide multimeter indication by standard resistor test report value.
Calculated value will be between 99.99664 and 100.00336 A.
(14) Repeat technique of (9) through (13) above using standard resistors and
settings listed in table 6. Calculated values will be within limits specified.
