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).
- Up to 100MΩ in 100Ω stop
- Low voltage coefficient
Variation of the resistance value is less than ±0.1% at 1MΩ and 10MΩ steps against 100V application, and less than ±0.04% at 100Ω 1Ω 10Ω, and 100Ω flaps against 10V application.
- Shock and vibration proof construction
- Easy-to-read in line indication
- Best suited for calibration of insulation resistance testers and 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 ± 1.1m at 0.1 setting.. 1 m 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 dail system, various types of resistance thermometers and bridges can te calibrated accurately and promptly.. Excellent ami shock and -vibration properties
