1.5 Power
The DCT-7088 is a DC powered instrument that normally operates from an internal 12 volt
battery supplied with the unit. It may also be powered by one of the following sources
which connect to the 12-15 volt DC input on the breakout box:
!
Battery charger/AC adapter (converts a 90 to 264 volt AC, 50/60 Hertz, 15 watt input
to a 15 volt DC output)
!
Automobile cigarette lighter adapter (provides a 12 volt DC output from an automobile
cigarette lighter jack)
If the battery charger/AC adapter is connected, it simultaneously powers the flowmeter and
recharges (or maintains the charge) on the internal battery. The battery charges at a slower
rate when the battery charger/AC adapter is used to both power the unit and charge the
battery.
For more information on the breakout box, refer to Section 2.1.
1.5.1 FUSES
The design of the flowmeter includes the following 3-ampere fuses:
!
One located on the front panel of the flowmeter in the upper right corner
(Figure 1-3) to protect against overcurrent or short circuits from the internal battery
!
One located in the breakout box to protect against overcurrent from the output of the
battery charger/AC adapter
The fuse inside the breakout box is accessible by removing the four screws securing its
cover. Power should be disconnected prior to replacing any fuse.
