005/6/8
VERY HIGH ACCURACY DECADE BOXES WITH
VERSATILE WIDE OHM RANGE
Resistance Decades & Standards
A versatile range of resistance decade boxes available in 5, 6 & 8
decades. High Accuracy and wide range 0.001 ohm to
11 Mega ohm are combined in a compact lightweight metal
case. The switches have gold plated contacts to ensure a low
contact resistance and negligible thermal E.M.F. Some models
employ the Waidner Wolf technique to eliminate the errors switch
contact resistance and are particularly suited to Pt100 simulation
with resolution as low as 0.001 ohm (» 0.0025°C).
