The 1040 is an accurate hand held decade resistance box designed to meet the needs of industry and
education. Housed in a robust metal case the compact construction makes it easily portable.
Excellent accuracy is achieved by using high stability metal film resistors. Mid-scale accuracy is 0.1%. The
8-digit thumbwheel switch enables precise setting with a clear unambiguous indication of the resistance value.
The temperature coefficient is better than 50 ppm per ºC. Each resistor has a power rating of 1 watt.
Switch Contacts: Special attention has been given to reliability. A special multiple gold contact switch
arrangement ensures that back-up contacts are always available to take over should a contact fail.
Safety Terminals: Fully compatible with 4mm shrouded plugs, as well as standard plugs, bare wires, and
spade terminals.
Clear Visual Indication: To prevent misreading, the 1040 incorporates a colour coding system to divide the
display into 3 groups to indicate ohms, Kilohms, and Megohms.
Added Protection: The 1040 comes fitted with an ergonomic rubber boot (9028) providing increased
protection and durability. The boot has a textured grip for comfortable handling and a raised edge so the 1040
angles slightly upward when resting horizontally. This improves visibility as well as gripping the surface,
meaning no movement when thumbwheel switches are pressed. It is easily removable if required.
Due to continuous development Time Electronics reserves the right to change specifications without prior notice.
