79. Specified with aperture Auto and open input terminals. For all ranges and for ≥1k sample rate, add an additional 3× RMS noise uncertainty to ppm of range.
80. Specified with aperture Auto, 100 Hz sine wave for sample rate ≤ 5 k, and 1 kHz sine wave for sample rate ≥ 10 k. Distortion is calculated using first five harmonics. For the 1 A, 3 A, and 10 A ranges,
use the 100 mA range accuracy; guaranteed by design.
81. Specified with aperture Auto, 100Hz sine wave for sample rate ≤5k, and 1kHz sine wave for sample rate ≥10k. For the 1A, 3A, and 10A ranges, use the 100mA ENOB; guaranteed by design.
82. Sample rate is not continuously adjustable. For valid discrete settings, see the Model DMM7510 Reference Manual.
