a. Performance Check
(1) Connect TI KΩ input to calibrator OUTPUT HI and TI COM input to calibrator
OUTPUT LO.
(2) Press TI mA/V, KΩ/nS pushbutton to KΩ/nS (in).
(3) Press TI 200 Ω range pushbutton.
(4) Set calibrator for a 190 Ω nominal output.
(5) Rotate calibrator knob below EDIT FIELD pushbutton to adjust calibrator
display indication to equal TI indication. Calibrator err display will indicate within limits
(6) Repeat technique of (3) through (5) above, using calibrator outputs and TI
