Manufacturer: Yokogawa

Model: 279303

Warranty: 12 months


Resistance Range: 0 to 111.1110 MΩ

Dial Composition: 100 Ω × 10 + 1 kΩ × 10 + 10 kΩ × 10 + 100 kΩ × 10 +

1 MΩ × 10 + 10 MΩ × 10

Accuracy: 100 Ω, 1 kΩ, 10 kΩ, and 100 kΩ step: ± (0.05% + 0.05 Ω);  1 MΩ and 10 MΩ step: ± 0.2% (At temperature 23 ± 2°C, humidity below 75%, ; incuding residual resistance approx. 0.05 Ω)

Temperature Coefficient: Variation 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: 100 mA (100 Ω step), 30 mA (1 kΩ step), 10 mA (10 kΩ step), 3 A (100 kΩ to 600 kΩ step),2000 V (700 kΩ to 1 MΩ), 2000 V (1 MΩ step), 2000 V (10 MΩ step).

Insulation Resistance: More than 10^11 Ω (at 1000 VDC) between panel and circuit.

Dielectric Strength: 2500 VAC 1 minute between panel and circuit.

Dimensions: Approx. 116 × 497 × 140 mm

Weight: Approx. 4.8 kg
