- Minimum difference of 0.1 g/cm
3
between the density of the D4 fluid and the
density of the D3 fluid. The density of the D4 fluid must be greater than the
density of the D3 fluid.
- Minimum difference of 0.1 g/cm
3
between the density of the D4 fluid and the
density of water. The density of the D4 fluid may be either greater or less than
the density of water.
• Before performing the calibration, record your current calibration parameters. If the
calibration fails, restore the known values.
