5. Operation
The MAG 8000 & MAG 8000 CT is factory configured for 6 years of typical operation on the internal
battery pack. High or low temperature, frequent use of IrDA communication, high pulse output
rate, and high excitation frequency in leakage detection mode will reduce actual operation time.
The MAG 8000 & MAG 8000 CT power management function controls each power consuming
element and measures the temperature for optimal calculation of remaining battery power
capacity.
The battery figure (generated as customer parameter list - see section 4 "Commissioning") shows
power management information.
At each new battery replacement the capacity is reset to 100% (Flow Tool parameter FT508-
FT510) which is then reduced with the real meter consumption each 4 hours.
The battery limit (FT206) is the level where the low power alarm is activated and generates an
alarm or call up (if configured).
Power status (FT513) follows the battery symbol on the display.
When changing battery power from internal to external battery packs, or visa versa, "Battery
power" (FT507) must be adjusted to match the actual number of batteries connected.
SFIDK.PS.026.D9.02
The battery power capacity for operation is
indicated in 3 levels.
• Full symbol indicates the battery capacity is
above the battery alarm level (% preset
parameter FT206).
• Low symbol indicates that the battery should
be replaced; however, the measurement
will remain active. The level is based on a
preset alarm level.
• When the low symbol is flashing the mea-
surement and communication is disabled
until the battery pack has been replaced and
reset.
The "Low battery" is a selectable % parameter
(FT206) of 100% full capacity. The meter calcu-
lates the remaining capacity every four hours,
including all consuming elements and influ-
ence of change in temperature.
