Yokogawa 279301十进位电阻箱（0.100~1111.210Ω）

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)

Max. Allowable Power: 0.25 W per step. Within 1 W for overall instrument.

Max. Allowable Current: 50 mA (100 Ω step), 150 mA (10 Ω step), 500 mA (1 Ω step), 1.5 A (0.1 Ω step).

Insulation Resistance: More than 500 MΩ (at 500 VDC) between panel and circuit

Dielectric Strength:1000 VAC 1 minute between panel and circuit

Dimensions: Approx. 116 × 497 × 140 mm
