YOKOGAWA *YOKOGAWA Decade Resistance Boxes 2793 (#279301)

Maker : YOKOGAWA Model No. : 279301 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 ± 2ºC, humidity 45 to 75%) Input Power: Max.0.1 W Max. Allowable Power : 0.25 W per step Within 1 W for overall instrument Insulation Resistance : More than 500 MΩ (at 500 VDC) between panel and circuit Dielectric Strength : 1000 VAC 1 minute between panel and circuit Model 2793 decade resistance box is high-accuracy, stable DC variable resistor with 6 dials and is available in two styles: 279301 for medium resistance from 0.1 to 1,111.210 Ω in 1 mΩ steps (best suited for calibration of resistance thermometers or bridges); 279303 for high resistance from 0 to 111.1110 MΩ in 100 Ω steps (suitable for calibration of insulation resistance testers or bridges). High accuracy and stability High reproducibility Excellent reproducibility is obtainable because dial switches with low contact resistance are used. For example, changes in contact resistance is within ± 1.1mΩ at 0.1Ω setting. 1 mΩ resolution Simple, quick dial operation In-line display for city reading Ideal for calibration of resistance thermometers and brides Due to its high accuracy and a dial system, various types of resistance thermometers and bridges can be calibrated accurately and promptly. Excellent anti shock and -vibration properties
