1.For sinewave inputs between 1,000 and 10,000 counts, add to number of counts 100 counts for frequencies 20 Hz to 20 kHz, 200 counts for 20 kHz, and 500 counts for 50 kHz to 100 kHz.

2.Relative to calibration standards.

MEDIUM AND FAST READING RATES	........In medium rate, add 50 counts to number of counts. In the
	fast rate the specifications apply for sinewave inputs
	≥1000 (4½ digit PRGH￿ FRXQWV and >100 Hz.
NONSINUSOIDAL INPUTS	For nonsinusoidal inputs ≥10,000 counts with frequency
	components ≥100 kHz, add the following % of reading to
	the accuracy specifications.
