Temperature and Velocity (2.11.1.)
Transducer selector (2.11.1.1.)
Sets the transducer index for all parameters applicable to this sub-menu.
Sound velocity (2.11.1.2.)
Enters the value adjusted based on parameter Sound Velocity at 20°C (2.11.1.7.)
(Page 220) vs. Process Temperature (2.11.1.3.) (Page 218) characteristics of air.

• Auto sound velocity (2.11.1.8.) (Page 221)
• Sound velocity at 20°C (2.11.1.7.) (Page 220)
Alternatively, enter the current sound velocity (if known), or perform a Auto Sound Velocity
(2.11.1.8.) (Page 221) calibration. The units are in m/s if Units (2.1.1.) (Page 162) = meters,
centimeters, or millimeters; if Units (2.1.1.) (Page 162) = feet or inches, then they are in ft/s).
Note
If this value is set to 0, the device will be unable to measure. Perform a master reset to
recover to default values.
Process temperature (2.11.1.3.)
Displays the transducer temperature in °C.

• Fixed temperature (2.11.1.6.) (Page 220)
If Temperature Source (2.11.1.4.) (Page 219) is set to any value other than Fixed
Temperature, the value displayed is the temperature measured. If Temperature Source
(2.11.1.4.) (Page 219) is set to Fixed Temperature, the Fixed Temperature (2.11.1.6.)
(Page 220) value is displayed.
