Measurement Performance

Density calibration fluids

D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-density) fluid. You may use air and water. If you are calibrating a T-Series sensor, the D1 fluid must be air and the D2 fluid must be water.

CAUTION

For T-Series sensors, the D1 calibration must be performed on air and the D2 calibration must be performed on water.

For D3 density calibration, the D3 fluid must meet the following requirements:

•Minimum density of 0.6 g/cm3

•Minimum difference of 0.1 g/cm3 between the density of the D3 fluid and the density of water. The density of the D3 fluid may be either greater or less than the density of water

For D4 density calibration, the D4 fluid must meet the following requirements:

•Minimum density of 0.6 g/cm3

•Minimum difference of 0.1 g/cm3 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/cm3 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
