a. Performance Check
(1) Connect calibrator OUTPUT HI and LO to TI front Input HI and LO.
(2) Connect calibrator SENSE HI and LO to TI front Ω4W Sense/Ratio Ref HI
and LO.
(3) Press Shift key then FUNCTION Ω 2W/Ω 4W key.
(4) Press Shift key then RANGE/DIGITS Auto/Man key to select 6 digits
resolution.
(5) Set calibrator for a 0 Ω output, EX SNS on, and 2 wire Comp off.
(6) Press RANGE/DIGITS ∧ or ∨ key to select ranges listed in table 5. If TI does
