The RM6-N is a space and cost-saving 6 decade resistance box . 3 models are available covering the range 1ohm to 111.111 Megohm. An additional 1kohm resistor is available at the terminals enabling the user to make a simple divider. The RM6-N incorporates 0.6 watt metal film resistors with a specified accuracy of ±1%. The maximum permissible voltage is 250 V d.c. 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-Ns constitute an ideal tool for use in all electrical and electronic laboratories or workshop environment offering a wide range of values with minimum cost.
