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.
Safety Terminals
Compatible with 4mm shrouded plugs, as well as standard plugs, bare wires, and spade terminals.
Added Protection
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 wide range and high accuracy make the 1040 one of the most popular models in the Time Electronics resistance decade box range. It is easy-to-operate, portable, and gives the user precision and reliability across applications.
