• 1 O – 100 MO
• High accuracy
• Clear visual indication
• High stability and low temperature coefficient
• Compact and robust

The 1040 is an accurate hand held decade resistance box designed to meet the needs of industry. 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.

To prevent misreading, the 1040 incorporates a colour coding system to divide the display into 3 groups to indicate ohms, Kilohms, and Megohms.
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.
