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).

The HydroRanger 200 uses the TS-3 temperature sensor assigned to the transducer. If
one is not connected, the ultrasonic/temperature transducer is used. If the transducer
does not have an internal temperature sensor, the Temp Fixed (P661) value is used.
If the acoustic beam atmosphere temperature varies with distance from the transducer,
connect a TS-3 Temperature Sensor and ultrasonic / temperature transducers, and select
average.
