FFM100 User’s Manual
Page 16 Revision 1.2
is programmed with the appropriate value for thermal expansion coefficient of the fluid being
measured. The default value of this field is (0.083%/°C), which is appropriate for diesel fuel.
The configuration tools have predefined values for common fluids: diesel, engine oil, gasoline,
and water. You may select one of these values or choose your own.
3.5.6 Configuring Channel #1 Data Damping Period
NOTE: This parameter is available only when the Operating Mode of the FFM100 is set to
“Two Independent Flow Rates”.
You can configure a damping parameter to smooth the flow rate readings or make them more
responsive. The data damping is configurable between 0.2-25.0 seconds. The default data
damping period is 3.0 seconds.
3.5.7 Resetting the Total Volume Recorded for Channel #1
NOTE: This parameter is available only when the Operating Mode of the FFM100 is set to
“Two Independent Flow Rates”.
The FFM100 maintains the total volume recorded in EEPROM, so that it is maintained across
power cycles. Select this menu entry to reset the total volume recorded to zero.
3.5.8 Configuring Channel #1 Temperature Instance
Program this parameter to match the desired instance number of the temperature reading for
this channel. You can program this parameter to any value between 0 and 252. The default
value for this parameter is 0.
3.5.9 Configuring Channel #1 Temperature Source
Program this parameter to match the desired instance number of the temperature reading for
this channel. You can program this parameter to any value between 0 and 252. The default
value for this parameter is 129 (User Defined).
3.5.10 Configuring Channel #1 Temperature Label
Program this parameter with a text string which identifies the particular temperature parameter
being monitored by this channel. Maretron display products will display this label text when
you are selecting data to display.
4 Maintenance
Regular maintenance is not required; however, an occasional inspection will ensure continued
proper operation of the Maretron FFM100. Perform the following tasks periodically:
• Clean the unit with a soft cloth. Do not use chemical cleaners as they may remove
paint or markings or may corrode the FFM100 enclosure or seals. Do not use any
cleaners containing acetone, as they will deteriorate the plastic enclosure.
