CAUTION! The indicator has circuitry that when used with the external power
supply, recharges the Ni-Cad or NiMH batteries. Therefore, DO NOT connect a
power supply to the indicator if using alkaline batteries.
8432-CH SETUP INSTRUCTIONS
AC Power Supply
To operate the 8432-CH scale without batteries, connect the 12 VDC 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. 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 AC power supply is also used to recharge the batteries in the
indicator, when the scale is operated from Ni-Cad or NiMH batteries.
Batteries
Battery operation is a standard feature of the Detecto 750 indicator used on the scale,
although the batteries are optional (not included). The indicator can be operated from 6 "AA"
size Alkaline, Ni-Cad or NiMH batteries. The batteries are contained in a battery holder inside
the indicator which is accessible by removing a panel on the back of the indicator.
When using batteries, all 6 batteries must be of the same type. They must be all Alkaline, all
Ni-Cad or all NiMH. In addition, DO NOT mix Ni-Cad or NiMH batteries.
Battery Operation
The scale 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). A bar graph on the display shows 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. If using Ni-Cad or NiMH batteries connect the AC power supply to the
indicator and then plug it into the proper electrical outlet to begin charging the batteries.
Battery Charging
The AC power supply must be plugged into a proper electrical outlet and connected to the
indicator for approximately 8 to 10 hours to fully recharge the batteries. Note that while the
batteries are charging the indicator can still be operated and that charging the batteries for
more than 10 hours will not damage them.
