Recommended minimum scale factors for time, volume and flow on graphical output
| Instrument display | Hardcopy graphical output | |||
| Parameter | Resolution required | Scale factor | Resolution required | Scale factor |
| Volume# | 0.050 L | 5 mm·L−1 | 0.025 L | 10 mm·L−1 |
| Flow# | 0.200 L·s−1 | 2.5 mm·L−1·s−1 | 0.100 L·s−1 | 5 mm·L−1·s−1 |
| Time | 0.2 s | 10 mm·s−1 | 0.2 s | 20 mm·s−1 |
#: the correct aspect ratio for a flow versus volume display is two units of flow per one unit of volume.
