Product Highlights

The model RM8 decade resistance box is designed to compliment our range of resistance boxes, offering a very wide range 0.01 ohm to 1 Mega ohm in a compact and versatile unit. The low decade steps of 0.01 ohm enable very high resolution, when simulating resistance values and the power rating is 1.0 watt per coil. The RM8 uses double pole switching to minimize the effects of contact resistance. The lower value decades (0.01 and 0.1 ohm) are manufactured from Manganin resistance wire and the other decades from selected metal film resistors. This offers good stability combined with excellent load and temperature coefficients. Housed in a hardwood case with metal panel the size is only 254 x 145 x 80mm and the connections are with 4mm binding posts that will accept spade or banana plugs.

  • Terminals:
    • 2 binding posts will accept 4mm banana plugs and spade tags
    • 1 terminal for connection to panel/earth
  • Dimensions: 254mm x 145mm x 80mm (W H D) approx
  • Mass: 0.95 kg
  • Resistors:
    • Power Rating: 1 watt per resistor
    • Lower decades (0.01 & 0.1 ohm) Manganin wire wound, other decades metal film
    • Temperature coefficient: 10ppm/°C
  • Switches: Rotary 2 poles in parallel, contacts silver plated brass with positive click mechanism. Insulation >50,000 Mega ohm
  • Residual Resistance: < 0.1 ohm
  • Test Voltage: 1kV dc between terminals and panel
