External Power
The IETG FlowHawk
™
can receive power from an external DC
power source. However, any connection of external power to the
monitor must occur through a standard external modem unit (EMU,
p/n 3800-0148) or an EMUX (EMU/multiplexer, p/n 106226E) for
compliance with IS certification.
Note: When installing an externally-powered EMU or
EMUX, IETG recommends locating the EMU or EMUX
in close proximity to the DC power source to maximize the
net power available to the EMU/EMUX.
Note: The externally-powered FlowHawk, EMU, and
EMUX are not equipped with backup power. Therefore,
in the event of an interruption or loss of power at the
power source, the monitor will discontinue taking readings
until power is restored. However, a loss of power will not
result in a loss of data. The monitor will retain all stored
data in memory.
