Five-Point Analog Calibration Worksheet
Record as-found and as-left engineering readings against five signal points, calculate tolerance results and save a local job.
Worked example
For a 0–100 PSI range, 12 mA corresponds to 50 PSI. With a tolerance of 0.5% of span, the allowed error is ±0.5 PSI at every point. Select the tolerance basis required by the instrument and site.
| Point | Applied | Expected | As found | Error / result | As left | Error / result |
|---|---|---|---|---|---|---|
| 0% | 4 mA | 0 PSI | Untested | Untested | ||
| 25% | 8 mA | 25 PSI | Untested | Untested | ||
| 50% | 12 mA | 50 PSI | Untested | Untested | ||
| 75% | 16 mA | 75 PSI | Untested | Untested | ||
| 100% | 20 mA | 100 PSI | Untested | Untested |
Pass means the entered error is inside the selected tolerance only. It does not include reference-instrument uncertainty or establish traceability. Follow the approved calibration procedure.
