Resistance Box, Plug Pattern
All plugs are turned to a fine standard taper and are interchangeable. These are moulded in fluted plastic tops. The brass blocks are undercut and are fitted to a thick insulating plate. Heavy 4 mm brass terminals are used. Coils are non-inductively wound and are treated to be strain-free. Coil values are engraved on the plate and an infinity plug is also included. Accuracy ±0.5% for 0.01 to 0.05 ohm coils, ±1% for the rest.
