NOTES:
(1) 8B33 and 8BP01, 8BP02, 8BP04, 8BP08, 8BP16, XEV rating only. Backpanels obtained from
other sources may have lower ratings.
(2) For 1 to 25 seconds the max allowable transient current rating is √2500/(event time). For less
than 1 second, ANSI/IEEE C37.90.1 applies with a 0.05
Ω load. For greater than 25 seconds, the
2 Arms continous rating applies.
(3) At standard 60Hz factory calibration. Consult factory for calibration at other frequencies.
(4) For 0-10% Span measurements, add 0.25% accuracy error (-02 through -07) or 1.00% accuracy
error (-01). Accuracy includes linearity, hysteresis and repeatability but not source or external
shunt inaccuracy (if used).
