Manufacturer: Yokogawa
Model: 279301
Warranty: 12 months
Resistance Range: 0.100 to 1111.210 Ω
Dial Composition:0.001 Ω × 10 + 0.01 Ω × 10 + 0.1 Ω × 11 + 1 Ω × 10 + 10 Ω × 10 + 100 Ω × 10
Resolution: 0.001 Ω
Accuracy: ± (0.01% + 2 mΩ) (At temperature 23 ± 2°C, humidity 45 to 75%; Input Power: Max.0.1 W)
Temperature Coefficient α20 (x 10-6/°C):−5 to +10
Temperature Coefficient β20 (x 10-6/°C): less than -0.7
(Change of resistance with temperature is expressed by the following equation: Rt = R20 [1 + α 20 (t - 20) + β (t - 20)²] where Rt: resistance value at t °C; R2o:Resistance value at 20°C)
