Notes:
1. Stability specifications are included in the Absolute Uncertainty values in the primary specification tables.
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:
- Calibrate at 20 °C: Temperature coefficient adder is not required unless operated below 15 °C or above 25 °C.
- Calibrate at 26 °C: Add 2 °C temperature coefficient adder. Additional temperature coefficient adder is not required unless operated
below 21 °C or above 31 °C.
3. Refer to current derating factors table for loads outside of this range.
4. Active two-wire compensation may be selected for values less than 100 k , with either the front panel or the meter input terminals as
reference plane. Active compensation is limited to 11 mA load, and to 2 V burden. Two-wire compensation can be used only with
meters that source continuous (not pulsed) dc current.
