Yokogawa / Decade Resistance Box / 2793 
Model 2793 is high-accuracy, stable DC variable resistor with 6 dials and is ava
ilable 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); 2
79303 for high resistance from 0 to 111.1110 MΩ in 100 Ω steps (suitable for c
alibration of insulation resistance testers or bridges).
