* Error in power mode will not exceed twice the linear accuracy specification
Accuracy specifications apply within the following limits, based on reading rate:
Slow Reading Rate: Between 15,000 and 99,999 counts (full range)
Medium Reading Rate: Between 1,500 and 30,000 counts (full range)
Fast Reading Rate: Between 150 and 3,000 counts (full range)
