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 or use the internal rechargeable battery pack. Refer to the
POWER SUPPLY or BATTERY sections of this manual for more instructions.
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

The scale is shipped with an internal rechargeable battery pack (7.2VDC, 700 mA). The battery
is contained in a cavity inside the scale. Access is via a removable cover on the bottom of the
scale. The PS-7 can operate for up to 20 hours of continuous use with a fully charged battery
pack. Full charging the rechargeable battery pack before the first use is necessary.

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 8.5 hours to fully recharge the battery pack in
the scale. While the batteries are charging the PS-7 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 8.5 hours will not damage it but the lifetime of
rechargeable battery pack may be shortened.
If the power supply is disconnected before the 8.5 hours, the scale will continue to charge the
battery pack when the power supply is plugged back in.
