Time 1040 Wide Range Resistance Decade Box
Includes: Time 1040 resistance decade box, protective cover (fitted) and user manual.
The Time 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.
Resistance is simulated by dialling the value required using the thumbwheel switches. This enables precise setting with a clear unambiguous indication. For example — to simulate 3k83 set the 1k bank to 3, the 100Ω bank to 8 and the 10Ω bank to 3, all the other dials set to zero.
Special attention has been given to the problem of reliability of operation. A special multiple gold contact switch arrangement ensures that a back-up contact is always available to take
over should a failure occur.
