A five decade capacitance box to complement the RM6-N range of resistance decades.

Styled in the same ergonomic desk case, the CM5-N decade resistance box is a useful addition to any laboratory, as well as for industrial and educational use.

The required capacitance is set by means of rotary switches with skirted knobs and stators giving a clear indication of the dial setting.

The capacitors are a combination of polycarbonate and polystyrene, generously rated minimum 160 Vdc with a good dissipation factor and high insulation.

A useful feature of this unit is the residual capacitance being compensated for on the 10 x 100pF and 10 x 1nF dials so that the actual value of the dial setting appears at the terminals.
