The Time Electronics 1040 is a precision wide-range resistance decade box designed to meet the requirements of both industry and education. It's compact and durable, housed in a robust metal case with a removable protective rubber cover, making it ideal for use in both the laboratory and the field. Excellent accuracy (0.1% mid-scale) is achieved by using high stability metal film resistors. The 8-digit thumbwheel switch allows simple and precise setting with a clear indication of the resistance value.
Switch Contacts: Special attention has been given to operational reliability. A special multiple gold contact arrangement ensures low contact resistance and continued operation, even if a contact fails.
Clear Visual Indication: To make setting and reading easy, the 1040 incorporates color-coded digits: megohms - red, kilohms - yellow, ohms - white.
Safety Terminals: The terminals are compatible with 4 mm 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 for labels. It's easy to remove if you prefer a stand-alone unit or to house the 1040 in the optional 9026 carry case.
