An automated safety monitoring system for a chemical processing plant accepts vessel pressure readings from 120 kPa to 155 kPa inclusive. The system outputs "SAFE" if the pressure is within this valid range, and "WARNING" if it is not.
The monitoring algorithm is verified using various types of test data.
Complete the table below by providing one suitable example of test data (Pressure) for each specified type of test.
| Test data (Pressure) | Type of test | Expected output |
|---|---|---|
| Normal | "SAFE" | |
| Boundary | "SAFE" | |
| Erroneous | "WARNING" |
