AC NOTES
1. Specifications are for SLOW rate and sinewave inputs >5% of range.
2. Speeds are for 60Hz (50Hz) operation using factory default operating
conditions (*RST). Auto zero off, Auto range off, Display off, includes
measurement and binary data transfer out the GPIB.
3. 0.01% of step settling error. Trigger delay = 400ms.
4. Trigger delay = 0.
5. DETector:BANDwidth 300, NPLC = 0.01.
6. Maximum useful limit with trigger delay = 175ms.
7. Applies to non-sine waves >5Hz and <500Hz. (Guaranteed by design for
Crest Factors >4.3)
8. Applies to 0°–18°C and 28°–50°C.
9. For signal levels >2.2A add additional 0.4% to “of reading” uncertainty.
10. Typical uncertainties. Typical represents two sigma or 95% of manufac-
tured units measure < 0.35% of reading and three sigma or 99.7% <
1.06% of reading.
