Test Equipment
The following table lists the test instruments required for calibrating the TB-4302C.
| Instrument | Recommended Model | Requirements |
|---|---|---|
| DMM | PXI-4071 | Use a DMM that has an accuracy of 136 ppm or better when measuring 5 Ω in 4-wire mode. |
| 4-wire Kelvin probe | Keithley 5808 | Use a probe capable of measuring Kelvin resistance. |
Test Conditions
The following setup and environmental conditions are required to ensure the TB-4302C meets published specifications.
- Keep connections to the device as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements
- Maintain an ambient temperature of 23 °C ±5 °C. The device temperature will be greater than the ambient temperature.
- Keep the relative humidity below 80%.
Device Setup
- Loosen the two jackscrews and remove the cover from the TB-4302C.
- Launch the Calibration Executive procedure. Calibration Executive guides you through the required connections.
Test Limit Equations
The following test limits are derived from the published specifications.
| Equation Type | Equation |
|---|---|
| Shunt Value Accuracy Verification | TestLimit = TestValue ± [TestValue * (GainError / 100)] |
