1.Specifications apply to displayed value.
2.Temperature coefficient is an adder to uncertainty specifications that does not apply unless operated more than 5°C from calibration temperature, or calibrated outside the range 19°C to 24°C. Two examples:
a)Calibrate at 20°C: Temperature coefficient adder is not required unless operated below 15°C or above 25°C.
b)Calibrate at 26°C: Add 2°C temperature coefficient adder. Additional temperature coefficient adder is not required unless o perated below 21°C or above 31°C.
3.Refer to current derating factors table for loads outside of this range.
4.Active
source continuous (not pulsed) dc current.
