INSTALLATION
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 a 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. Note that charging the
battery pack for more than 8 hours will not damage it.
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
When the 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 the power supply into the scale and then into the proper
electrical wall outlet. The scale will begin charging the battery pack.
