This instrument employs the double Kelvin Bridge principle for accurate measurement of low resistances. Twin, 5-position ratio arm, combined with a decade & slide wire, provide a wide range of resistance measurement, i.e. 0.2 micro-ohms to 11 ohms with high accuracy. Two or four terminal measurements may be employed. Current up to 10 A can be used during measurement. All controls are simple to operate. Thermal e.m.f. may be taken into account using the three position (Normal Off Reverse) current switch. Both ratio arms are operated by one switch. The press keys give full and reduced sensitivity control for the galvanometer detector. Readings are obtained direct from decade and slide wire scale multiplied by ratio arm switch setting. All dials, keys & terminals are positioned on a instrument panel mounted in polished wooden case with hinged lid
