Excellent reproducibility is obtainable because dial switches with low contact resistance are used. For example, changes in contact resistance is within +- 1.1m Ohms at 0.1 Ohms setting.
1 m Ohms 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.
