Notes:
1. Specifications apply to displayed value. 4-wire connections, except 100 m
Ω
.
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 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 kΩ, with either the front panel
or the meter input terminals
as
reference plane. Active compensation is limited to 11 mA load, and to 2V burden. Two wire compensation can be used only with Ω meters that
source continuous (not pulsed) dc current.
