Temperature Compensation (P660 To P664) - Siemens airanger DPL PLUS Instruction Manual

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 or 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.
