Parameters

P652 Offset Correction

The value altered when an Offset Calibration is performed.

Alternatively, if the amount of Offset Correction required is known, enter the amount to be

added to the Reading before display.

P653 Velocity

The value adjusted based on the Sound Velocity at 20 °C (P654) vs. Temperature (P664)

characteristics of air.

Alternatively, enter the current sound velocity (if known), or perform a Sound Velocity

Calibration (P651). The units used are m/s if P005 = 1, 2, or 3 (ft/s if P005 = 4 or 5).

P654 Velocity at 20°C

This value is used to automatically calculate Sound Velocity (P653).

After performing a Sound Velocity Calibration, check this value to verify the acoustic

beam atmosphere is air (344.1 m/s or 1129 ft/s).

Alternatively, if the acoustic beam atmosphere sound velocity at 20°C (68 °F) is known,

and the sound velocity vs. temperature characteristics are similar to that of air, enter the

sound velocity.

The units used are m/s if P005 = 1, 2, or 3 (or ft/s if P005 = 4 or 5).
