What's in the Box

  • Protective cover


The Time Electronics 1040 is 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.

The Time Electronics 1040 decade resistance box offers increment steps of 1Ω, over a range of 1Ω to 100MΩ. Special attention has been given to the reliability of operation for the 1040. A special multiple gold contact arrangement ensures low contact resistance and continued operation even if a contact fails.

To make selecting and reading the setting easy the 1040 incorporates color coded digits: megohms - red, kilohms - yellow, ohms - white. The 1040 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. The 1040 is compatible with 4mm shrouded plugs, as well as standard plugs, bare wires, and spade terminals.
