from the temperature sensor. Refer to your sensor documentation to confirm whether the
temperature sensor follows the Steinhart-Hart equation and to obtain the three coefficients to be
used (A, B, and C).
Channel 1, Channel 2, Channel 3 > Calculate Engineering Output
Set this to True to output engineering units for sensor frequency and sensor temperature (if a
thermistor is used). The CRVW3 applies a polynomial that works with most vibrating-wire
sensors. For details about the polynomial-based calculation process, refer to
NOTE:
To use a current barometric pressure reading as part of the calculation of water height,
pressure, or related measurements, refer to

Radio, Radio Power Schedule and Radio Advanced
When using a radio option, some key settings on the Radio, Radio Power Schedule and Radio
Advanced tabs should be set. See
Validating radio connectivity in the lab
(p. 27) and
(p. 51) for more details about these settings.
7.5.2 Managing changes to settings
Once you have made changes to the CRVW3 settings, click Apply at the bottom of the
Device
Configuration Utility
screen to save the settings. The CRVW3 will be busy for up to 20 seconds
while applying the changes. During this time, you will be unable to connect to the CRVW3. Watch
the LEDs on the device to determine when the device has completed its reconfiguration and has
resumed making measurements. See
(p. 39) for more information.
(Optional) Save the configuration to a file on the computer. Click Summary to display a summary
of the current settings. Click Save to save these settings to the computer as an XML file. The
default filename includes the device type and date. If needed, these settings can be reapplied at a
later time by clicking Read File then Apply.
