If the Calibrate Zero screen reads “Calibration Failure,” the sensor zero calibration was not 
successfully completed. “Calibration Failure” could indicate:

•

Flow of fluid during the sensor zero calibration

•

Partially empty flow tubes

•

An improperly mounted sensor

To clear a sensor zero failure:

•

Press 

 to exit the Calibrate Zero screen, then re-zero after correcting the problem, or

•

Abort the sensor zero procedure by cycling power to the platform

•

If appropriate, restore the factory zero or prior zero (see Section 16.3.1)

The Diagnostics menu is used to test the inputs and outputs. Figure 16-2 shows the Diagnostics menu. 
The Diagnostics menu is accessed through the Maintenance option of the Management menu.

Using the Diagnostics menu, you can:

•

Read the states of discrete inputs

•

Read the pressure and temperature values as received from external devices

•

Read the value of the frequency input

•

Set a specific value for discrete outputs, mA outputs, and the frequency output

Note: The Diagnostics menu is not the same as the diagnostic monitor. The diagnostic monitor, 
accessed through the View menu, allows you to read the values for tube frequency, left pickoff, right 
pickoff, drive gain, and live zero. The diagnostic monitor and its use are described in Chapter 17 and 
Chapter 22.
