AC Characteristics
Accuracy Specifications ±( % of reading + % of range )
[1]
[ 1 ] Specifications are for 90 minute warm–up, slow ac filter, sinewave.
[ 2 ] Relative to calibration standards.
[ 3 ] 20% overrange on all ranges, except 750 Vac, 3 A range.
[ 4 ] Specifications are for sinewave input >0.3% of range and > 1mVrms.
Add 30 μV error to AC voltage specification for frequencies < 1kHz.
750 VAC range limited to 8 x 10
7
Volt–Hz.
750 VAC range add 0.7 mV of error for each additional volt over 300 VAC.
[ 5 ] Specifications are for sinewave input >1% of range and > 10 µArms.
Frequencies > 5 kHz are typical for all ranges.
For the 3 A range (all frequencies), add 0.05% of reading + 0.02% of range to listed specifications.
Low Frequency Performance
Three filter settings are available: 3 Hz, 20 Hz, 200Hz.
Frequencies greater than these filter settings are specified with no additional errors.
