WINDOW FILTER AND MEMORY (BUFFER)
WINDOW FILTER SIZE: 0 to 10% of reading, where 0 averages all readings.
MEMORY: Up to 27.5 million timestamped readings with the compact buffer style, with additional
memory available using an external USB flash drive.
MAXIMUM INTERNAL MEMORY (Buffer): 27.5 million readings with the compact buffer style
(6½-digit without formatting), 11 million readings with the standard or full buffer style.
95. For DC voltage or 2-wire ohms to frequency or period, 10ms aperture. For AC current or AC
voltage, detector bandwidth is 300Hz.
96. Guaranteed by design; for digital I/O only.
97. Stimulus command required to meet specifications.
98. If using trigger model, add 200ns uncertainty.
99. For DC or AC coupled, the trigger level can be set up to 100% of measure range.
100. Rising or falling edge triggering supported. Window trigger requires setting two independent
levels.
101. Trigger event occurs after the threshold crossing at a time determined by total trigger
latencies.
102. Accuracy specifications require user A
CAL
and are verified with level trigger amplitude set to
50% of range with a 100Hz sine wave at 100% full scale of range. High frequency rejection
is off. NPLC 0.0005 (DC voltage/DC current) or aperture 1µs for digitize voltage or digitize
current. Specified for fixed range, autozero off. For digitized DC voltage AC coupled, add 0.5
%. For DC current and digitized DC current 3A or 10A ranges, add an additional 2%.
