a. Performance Check
(1) Connect calibrator OUTPUT HI to TI VOLTS/ input and calibrator OUTPUT
LO to TI LOW input.
(2) Press TI pushbuttons as listed in (a) through (c) below:
(a) k (in).
(b) 20 k range (in).
(c) HI LO (out).
(3) Set calibrator for a 19k
nominal output.
(4) Rotate calibrator knob below EDIT FIELD pushbutton to adjust calibrator
display indication to equal TI indication. If calibrator err display does not indicate within
limits specified in first row of table 11, perform 20 b below.
(5) Repeat technique of (2) (b) and (c), (3) and (4) above, using calibrator outputs
and TI settings and indications listed in table 11. Calibrator err display will indicate
within limits specified in table 11.
