a. Performance Check
(1) Position TI controls as listed in (a) through (c) below:
(a) AC DC pushbutton to DC (out).
(b) Ω pushbutton to ON (in).
(c) 200mV, 200A, 200Ω pushbutton to in position.
(2) Connect TI V-Ω input to calibrator OUTPUT HI and TI COM input to
calibrator OUTPUT LO.
(3) Set calibrator output to 190.0 Ω nominal (2-wire comp: ON).
(4) Rotate calibrator knob below EDIT FIELD pushbutton to adjust calibrator
display indication to equal TI indication. Calibrator err display indication will be within
limits specified in first row of table 6.
(5) Repeat technique of (1) (c), (3), and (4) above, using the settings and indications
listed in table 6. Calibrator err display indication will be within limits specified in table 6.
