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 or use the internal rechargeable battery pack. Refer to the
POWER SUPPLY or BATTERY 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
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 21 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.
Note that charging the battery pack for more than 8.5 hours will not damage it but the lifetime of
rechargeable battery pack might be shorter under such improper use.
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.
INSTALLING A REPLACEMENT BATTERY
When the scale can not be operated by a full charged rechargeable battery pack well (continue
to show “"73<” or automatically shut off during operation or not switch on….), it’s time to
replace the rechargeable battery pack.
1. Turn scale over so that display is facing
down and place it upside down on a flat
level surface, such as a table or bench.
2. Locate battery cover on bottom of scale.
3. Remove cover by pushing in on tab and
pulling up exposing battery snap connector.
4. Remove old battery and disconnect power
cable and then connect new battery.
5. Replace cover (it will click when locked in
place) and return scale to upright position.
6. Check scale for proper operation.
