- from 60% to 100% and from 100% to 60% of full load for model N6761A
- from 50% to 100% and from 100% to 50% of full load for model N6762A through N6766A)

1
Output current is derated 1% per °C above 40°C.
2
Applies when measuring currents that remain within the low range. Due to thermal settling, when transitioning
from measuring full-rated output current (the worst case), to measuring the current within the low range, the low
range accuracy specification is typically met within 5 seconds after the current has transitioned into the low
range. Accuracies within this 5 second settling period are typically 2X the specified accuracy or better.
3
When relay option 760 or 761 is installed on Models N6763Aand N6765A, the settling band is ±200 mV.
4
When relay option 760 or 761 is installed on Models N6764Aand N6766A, the settling band is ±350 mV.
