OPERATION

The FMG490 has a passcode system for restricting access 

to the menus. The meter comes  from the factory with the 

passcode set to 000000. When a user attempts to enter the 

menu system (see details on page 20), the passcode entry 

screen will be displayed.

The default passcode is 000000. If a different passcode has 

previously been set, then the user must enter that passcode 

at this time. After entering the passcode, or leaving it at 

000000 if using the default passcode, the user does the tap 

and hold sequence to move into the menu system.

To change the passcode

, you must use the 

THIRD MENU

 

screen. Access the 

THIRD MENU

 screen as follows:

• Enter the main menu system, as described above.

• On the main menu, tab over to the EXIT tab and tap

the 

 five times. A 

SUBMENU screen will display.

• On the SUBMENU screen tab over to the EXIT tab and

tap the 

 five times. The THIRD MENU screen will

display.

• To set the passcode, hold and tap and then use the

 and   to enter the new code. 

• Hold and tap again to return to the THIRD MENU

screen

• Tab to EXIT, and then hold and tap to return to the

SUBMENU.

To change the number of decimal places in the total

• To set the decimal point, hold and tap on SETD and then

use the   to move the decimal point.

To Change a Passcode and Decimal Places

PDAMP

PDAMP is used to view or change the number of samples 

for rolling average of pulse output.

TEST

TEST allows the user to initiate a fully functional, artificial flow 

rate for the purpose of testing other connected equipment. 

When TEST is applied, all features of the meter will function at 

the stated flow rate (in gallons per second).  
For TEST to function, the meter must be filled (not EMPTY 

PIPE).  
To enter a value into the TEST feature, navigate to the TEST 

tab and enter a flow rate value in the VAL screen (in gallons 

per second only,) then 

 

to the VAL box and   to the ON 

screen.  This will initiate the TEST feature.  The next   would 

bring you to the OFF screen, but you can ‘hold and tap’ 

the arrows to return you to the sub menu while the feature 

operates.
 

After use, the TEST feature must be turned OFF. 

If the TEST 

feature is not turned OFF, the stated static flow rate (in gallons 

per second) will be shown any time the meter is full or in a 

flowing condition. Flow values recorded by the meter while 

the TEST feature is operating are permanently recorded in the 

displayed TOTAL.  It may be useful to note that these values 

are only written to permanent memory every 15 minutes and 

cycling all power within this 15 minute time frame will return 

the meter to its previous total.

Power Indicators

A power indicator is displayed in the lower left of the main 

display window.
Any meter powered from an external power source will 

display a power plug icon when running on external power. 

If the connection to external power is lost, the meter will 

switch to the backup battery and the power icon will switch 

to a battery symbol.

OK

 on the battery indicator means battery voltage is above 

6.4 volts.

LO

 on the battery indicator means the battery is low and 

should be replaced soon.
