- Place the device in a known zero pressure environment.
- Access calibration settings in the device menu.
- Adjust the zero calibration if necessary.
- Record the calibration value for documentation.
- Connect a calibrated pressure source to the transmitter.
- Apply specific pressure values incrementally.
- Monitor and record the output signal for each value.
- Compare output readings with expected values for accuracy.
- Apply a sudden change in pressure to the device.
- Measure the time taken for the output signal to stabilize.
- Compare the measured response time with manufacturer specifications.
- Document any discrepancies for further analysis.
Configuration Check
- Obtain the operational requirements document.
- Cross-reference the transmitter configuration with requirements.
- Ensure all parameters are aligned with specified needs.
- Document any discrepancies for further action.
