AC POWER ADAPTER
To power the scale using the optional 110-240V AC 50/60 Hz 12V DC wall plug-in AC power
adapter, connect the small round plug from the AC adapter into the power jack on the back of
the indicator and then plug the AC power adapter into the proper electrical outlet. Refer to
Figure 1. On models requiring 240V AC, it is the customer’s responsibility to obtain the
correct AC power adapter plug.
BATTERY OPERATION
Batteries
The scale can use 6 "AA" size Alkaline, Ni-Cad or NiMH batteries (
not included
). You must
first obtain and install batteries before operations can begin. Batteries are contained in a
battery holder inside indicator. Access is via a removable panel on the back of indicator.
When using batteries, all 6 batteries must be of the same type. They must be all Alkaline,
Ni-Cad or all NiMH. In addition,
DO NOT
mix Ni-Cad or NiMH batteries.
IMPORTANT!
The scale can be operated from Alkaline, Ni-Cad or NiMH batteries.
All six (6) batteries must be of the same type. They must all be Alkaline, all Ni-Cad
or all NiMH.
DO NOT
mix Alkaline and Ni-Cad or NiMH batteries.
CAUTION!
The AC power adapter is also used to recharge the batteries, when the
scale is operated from Ni-Cad or NiMH batteries.
DO NOT
connect the AC power
adapter if using alkaline batteries. Also, when using alkaline batteries, make sure
the
0-3
setup option is disabled (set to 0). Refer to Setup and Calibration or
Setup Review sections of 750 Weight Indicator Owner’s Manual (8555-M483-O1).
Battery Status
The 750 indicator will operate for up to 250 hours on new Alkaline batteries or for up to 100
hours on fully charged Ni-Cad or NiMH batteries depending on the condition of the batteries
(from new to about 500 recharges). The battery bar graph on the display indicates the battery
capacity in 4 steps:
4 segments - the full battery capacity is available,
3 segments - the battery is at 75% of capacity,
2 segments - the battery is at 50% of capacity,
1 segment: - the battery is at 25% capacity.
When the battery voltage drops too low for accurate weighing, the indicator will show
!6;
and then shut off. You will be unable to turn the indicator back on until the Alkaline batteries
have been replaced or if using Ni-Cad or NiMH batteries, the AC power adapter is connected
to the display to operate it and recharge the batteries.
Battery Charging
To recharge the Ni-Cad or NiMH batteries, the AC power adapter must be connected to a
power outlet and plugged into the indicator. It will take approximately 8 to 10 hours to fully
recharge the batteries in the display. Charging the batteries for more than 10 hours
will not
damage them.
NOTE:
The indicator may be operated while the batteries are charging.
