Precision Low Ohm Resistance Box
- 0.01Ω to 1kΩ
- 10mΩ resolution
- Colour coded digits
- High stability and low temperature coefficient
- Ideal for Platinum Resistance Thermometer simulation Introduction The 1042 is a compact, robust and precision decade resistance box and will find many applications in both industry and education. The 1042 is particularly suitable for simulation of platinum resistance thermometers. Special attention has been given to the problem of reliability of operation. A special multiple gold contact arrangement ensures low contact resis- tance and continued operat ion even if a contact should fail. To prevent misreading, the 1042 incorporates a unique colour coding system to divide the setting into 2 units, MilliOhms and Ohms. Specification Resistance Range: 0.01Ω to 1kΩ in 0.01 ohm steps Zero Residual Resistance: 50mΩ maximum Residual Resistance Stability: less than 3mΩ Power Rating: 0.3 watt per resistor Maximum Working Voltage: 100 volts D.C. 70 volts A.C. (RMS) Maximum Current: 1 amp D.C. 0.7 amp A.C. (RMS) Connection: 4 mm terminals. A third terminal is provided to earth the case or to be connected to either terminal. Temperature Coefficient: 1R, 10R, 100R Decades –10ppm per °C 0.01R, 0.1R Decades – 65ppm per °C Dimensions: 110 x 75 x 200 mm Weight: 0.6 kg Optional Extras: Carry Case for field or industrial applications.
