INSTALLATION, Cont.
Power Supply
To power the weight indicator without batteries, connect the 12 VDC, 1 Amp power supply’s
connector into the power jack on the lower back of the indicator and then plug the power
supply into the proper electrical outlet. See Figure 1. On models requiring 220 VAC, it is the
customer’s responsibility to obtain the correct power adapter plug. The scale is now ready for
operation.
NOTE! The power supply is also used to recharge the batteries, when
the weight indicator is operated from Ni-Cad or NiMH batteries.
Batteries
Battery operation is a standard feature of the weight indicator, although the batteries are
optional (not included). The indicator can be operated from 6 "AA" size Alkaline, Ni-Cad or
NiMH batteries. You must first obtain and install batteries before operations can begin.
Batteries are contained in a battery holder inside the indicator. Access is via a removable
panel on the back of the 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.
CAUTION!
The weight indicator has internal circuitry that when used in
conjunction with the external power supply, recharges the Ni-Cad or NiMH
batteries. Because the indicator has this charging capability,
DO NOT
connect a
power supply to the indicator if using Alkaline batteries.
Battery Operation
The weight 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
"7<
and then shut off. You will be unable to turn the indicator back on until the Alkaline batteries
have been replaced or the AC power supply is connected to the display to operate it and
recharge the Ni-Cad or NiMH batteries.
Battery Charging
To recharge the Ni-Cad or NiMH batteries, the AC power supply 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.
