BURN-IN SCREENING

Burn-in screening is an option available for the models

indicated in the Ordering Information table. Burn-in dura-

tion is 160 hours at the maximum specified grade operating

temperature (or equivalent combination of time and tem-

perature).

All units are tested after burn-in to ensure that grade speci-

fications are met. To order burn-in, add “–BI” to the base

model number.
