Product Description:
A precision resistance decade box suitable for a wide range of simulation work. High accuracy, long term stability, and low temperature coefficient make the 1067 ideal for simulating and calibrating precision PT100 sensors and temperature indicators/meters that use resistive sensors.
Special care has been taken in the construction of this precision decade box to ensure that the residual end resistance is as low and as stable as possible. Multiple self-cleaning silver alloy contacts are used for each position to ensure outstanding performance and long life.
Housed in a robust metal case the 1067 is fully screened and low thermal emf terminals are used. The slim line design means it takes up minimum bench space and is easily transportable.
Resistance is selected by dialling the value required using the rotary switches. This enables precise setting with a clear unambiguous indication.
Each decade is scaled from 0 to 11 and therefore allows convenient overlap of the set values. The maximum value settable is 12,222.21 ohms.
Technical Specification:
| Range | 0 to 12kΩ |
| Resolution | 10mΩ steps |
| Number of Decades | 6, each decade settable from 0 to 11 |
| Accuracy | ± 0.01% of setting ± 2mΩ, after deduction of residual end resistance ±1mΩ for residual variation. At calibration temperature of 22°C. |
| Residual Resistance | Less than 10mΩ. Less than 1mΩ variation |
| Power Rating | 0.35 watt per resistor |
| Voltage Rating | Maximum 200V DC/AC RMS |
| Stability | 20ppm/year (>1Ω), 100ppm/year (<1Ω) |
| Current Rating | 10mΩ range: 3A, 100mΩ range: 2A, 1Ω range: 600mA, 10Ω range: 200mA, 100Ω range: 60mA, 1kΩ range: 20mA |
| Insulation | Case to resistance terminals 2kV / 50Hz maximum |
| Temperature Coefficient | Less than 10ppm/°C (> 1Ω). Less than 20ppm/°C (< 1Ω) |
| Operating Torque | Less than 0.1Nm |
