RM6N
SPACE SAVING, COMPACT & VERSATILE 6 DECADE
RESISTANCE BOX WITH WIDE RANGE
Resistance Decades & Standards
The RM6-N is a space saving 6 decade resistance box, 3 models
are available covering the range 1 ohm to 111,111 Mega ohm.
An additional 1 kilo ohm resistor is available at the terminals
enabling the user to make a simple divider. The RM6-N
incorporates 0.6 watt resistors with a specified accuracy of ±1%.
The maximum permissible voltage is 250 V dc. Designed for
durability and ease of maintenance, the case is high impact
polystyrene and the size is only 190 x 140 x 70 mm. The RM6-
N’s constitute an ideal tool for use in all electrical and electronic
laboratories or workshop environments offering a wide range of
values with minimum cost.
