Testing the Relays
From the keypad, the relay state can be switched. This can be used to test the interface with relays.
This is also described in Chapter 6 Troubleshooting.
To test the relays:
1. From the Main menu press 2. The 2.0 PORT SETUP menu title will appear.
2. Press 2, the Relay Setup option.
3. Press 3, for the Test Relays option.
4. Pressing 1 or 2 will toggle the states of the respective relays. The present state of the relays
are displayed in parenthesis.
Checking the Current Setup
The functions within menu level 5.0 provides a quick means of displaying the current system
parameters for the flowmeter. The flow rate and temperature units of measure, the state of the analog
outputs and relays or other critical information can be viewed from this menu.
To view the flow range, the flow rate units of measure and the area:
1. From the Main menu press 5. The 5.0 VERIFY menu title will appear.
2. Press 2, the Flow option. The sequence of information will be displayed to the screen as
shown in Figure 23. Press Enter twice to proceed. The first line of screen 1 is the window title.
Line 2, the Flow Factor is the conversion factor from the internal units of measure (SF/S) to the
desired units. Lines 3 and 4 show the flow range and the current flow units. Screen 2 shows
the standard density of the flow stream.
3. Press 4, the Area option. Screen 3, shown in Figure 23 will appear. The second line shows the
pipe area and units. The third line is the inside diameter of the pipe. (The third line will appear
only if the pipe I.D. is entered. If Std Velocity flow units are used the Area option is not
available.)

NOTE: The flowmeter does not measure standard density. This number is entered through menu
level 7.3.5. The standard density displayed in menu 5.2 must be equivalent to the standard
density of the process media. The factory has entered the process standard density supplied
at the time of order. The standard density factor is only used when calculation mass flow
units.
