17.5.6 Diagnostic monitor
The Diagnostic Monitor shows real-time values for sensor flow tube frequency, left and right pickoffs,
drive gain, and live zero.
Drive gain, pickoff levels, and sensor flow tube frequency values are useful for troubleshooting fault
alarms. For information about troubleshooting fault alarms, see Chapter 22.
Live zero is useful for monitoring the flow rate when it drops below the mass low flow cutoff. To
configure the mass low flow cutoff, see Section 7.3.2.
Note: The diagnostic monitor is not the same as the Diagnostics menu. The Diagnostics menu,
accessed through the Maintenance option of the Management menu, allows you to read the values of
external inputs and simulate output levels for outputs. The Diagnostics menu and its use are
described in Chapter 16.
