1040 Decade Resistance Box

A precision wide range resistance decade box designed to meet the requirements of both industry and education.  The 1040 is compact and durable, housed in a robust metal case with removable protective rubber cover, making it ideal for use in either the laboratory or field. Excellent accuracy (mid-scale 0.1 %) is achieved by using high stability metal film resistors. The 8-digit thumbwheel switch enables simple and precise setting with a clear indication of the resistance value. 

Switch Contacts: Special attention has been given to the reliability of operation. A special multiple gold contact arrangement ensures low contact resistance and continued operation even if a contact fails. 

Clear Visual Indication: To make selecting and reading the setting easy the 1040 incorporates colour coded digits: megohms - red, kilohms - yellow, ohms - white.

Decade Box Safety Terminals

Safety Terminals

The 1040 decade box features safety terminals that are compatible with standard plugs, 4 mm shrouded plugs, bare wires, and spade terminals.

These terminals are specifically designed with safety features including limited opening distance and a raised flange around the metal connection surface. This ensures that the clearances are sufficient to make the exposed metal parts touch-proof.

Decade Box Rubber Boot

Added Protection

This resistance substitution box comes fitted with an ergonomic rubber cover providing increased protection and durability. It has a textured grip for comfortable handling and side openings to place labels.

It is easy to remove if the user prefers a stand-alone unit or to house the 1040 in the optional 9026 carry case.
