GENERAL OPERATION
Power options
The MFC 4100 can be powered for portable operation by two each 9-volt alkaline, Lithium or NiMH
batteries. Alkaline batteries are standard with the MFC shipment. Meriam offers NiMH batteries and
charger cradles (external charge only) as an option. For bench top operations and download operations, an
AC adapter (P/N A36742) is recommended.
Located in the upper right corner of the display, this icon displays the
remaining battery power. Fresh batteries produce a full black cell body. As the power
drains, the black segment retreats indicating remaining power.
When the MFC is used with the optional AC adapter (P/N A36742), the battery circuit is bypassed
and a wall plug icon replaces the battery icon on the display header. The AC adapter jack is located
on the left side of the MFC.
NOTE: Power icons may temporarily disappear during certain HART Communication operations
