1. GENERAL
The 279301 and 279303 Resistance Boxes are high-accuracy variable resistors with 6 dials.
Setting of these instruments is easy over wide resistance range.
The 279301 has resistance range of 0.1 to 1111.210 Ω in 1 mΩ steps and
accuracy of ±0.01%.
It is best suited for calibration of resistance thermometers.
The 279303 has resistance range of 0 to 111.1110 MΩ in 100 Ω steps and
accuracy of ±0.05%.
It is best suited for calibration of insulation resistance testers.
These Decade Resistance Boxes employ in-line display system,
and rack-mounting is possible.
