range
400Ω 0～440Ω
3200Ω 420Ω～3600Ω
-10 ℃～ 18 ℃， +28 ℃～ 55 ℃ temperature coefficient,±0.005%FS/ ℃ .
Exciting current during measurement:
400Ω ： 1.0mA±10%;
3200Ω ： 0.2mA±10%;
Two-wire: Conductor resistance is excluded from errors.
Three-wire: Matching test line should be used. The total resistance of conductor should not be larger
than 25Ω.
