Unpacking
Before beginning installation of your scale, make certain the instrument has been received in
good condition. When removing the scale from its packing, inspect it for signs of damage, such
as exterior dents and scratches. Keep the carton and packing material for return shipment if it
should become necessary. It is the responsibility of the purchaser to file all claims for any
damages or loss incurred during transit.
1. Remove the scale from the shipping carton and inspect it for any signs of damage.
2. Plug-in the 15VDC adapter to use the scale and to begin charging the battery pack. Refer
to the Power Supply or Battery Pack sections of this manual for more instruction.
3. Place the scale on a flat level surface, such as a table or bench.
4. The scale is now ready for use.
Power Supply
To apply power to the scale using the supplied 15VDC,
300 mA power supply, insert the plug from the power
supply cable into the power jack on the back of the
scale and then plug power supply into the proper
electrical outlet. The scale is now ready for operation.
Battery Pack
The scale uses a 7.2VDC, 1200 mA built-in rechargeable battery pack. The PS-11 can operate
for up to 24 hours of continuous use with a fully charged battery pack.
Battery Charging
To recharge the battery pack, the power supply must be connected to an AC power outlet and
plugged into the scale. It will take approximately 8 hours to fully recharge the battery pack in the
scale. While the batteries are charging the PS-11 can still be operated.
Red light: The battery is charging.
Green light: The battery is fully charged.
When the scale is connected to the AC power supply, the charging light will flash three (3) times
between Red and Green and then turn Red and stay on indicating the battery is charging. Note
that if the battery is not connected to the scale, the charging light will turn off after flashing
between Red and Green.
Charging the battery pack for more than 8 hours will not damage it but the lifetime of
rechargeable battery pack may be shortened.
If the power supply is disconnected before the 8 hours, the scale will continue to charge the
battery pack when the power supply is plugged back in.
Low Battery (Lobat)
When the rechargeable battery pack is near the point it needs to be recharged, a low battery
indicator on the display will turn on. If the battery voltage drops too low for accurate weighing, the
scale will automatically shut off and you will be unable to turn it back on. When the low battery
indicator is displayed, the operator should plug-in the 15VDC adapter.
