(6) Reduce outputs to minimum and disconnect equipment setup.
b. Adjustments. Perform entire alignment procedure in paragraph 18.
18. Alignment
a. ADC Timing
NOTE
The alignment must be performed in its entirety. It must be
performed each time the TI is submitted for calibration. If both
alignment and performance checks have been done proceed to
paragraph 19.
(1) Connect TI to 110 V ac using the power supply supplied with TI.
(2) Press and hold USER key, press and release CLEAR key, then release the
USER key.
