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.
NOTES
62. For DC coupled, the trigger level can be set up to 100% of measure range.
63. Rising or falling edge triggering supported. Window trigger requires setting two independent levels.
64. Trigger event occurs after the threshold crossing at a time determined by total trigger latencies.
65. Accuracy specifications require user ACAL and are verified with level trigger amplitude set to 50% of range with a 100 Hz sine wave at 100% full scale of range. High frequency rejection is
off. NPLC 0.0005 (DC voltage/DC current) or aperture 1 µs for digitize voltage or digitize current. Specified for fixed range, autozero off. For DC current and digitized DC current 3 A range,
add an additional 2%.
