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 weight display, scale base assembly,
hardware pack and power supply from the shipping carton.
2. Remove the four leveling feet from the hardware pack and
install in each corner of bottom of scale base assembly.
Note:
Leveling feet must be in place to operate the scale.
3. For best results, place the scale on a flat level surface.
4. Adjust leveling feet, to ensure that the scale will sit level.
5. Plug-in 15VDC adapter to use scale and to begin charging
battery pack. Refer to POWER SUPPLY or BATTERY
PACK sections of this manual for more instruction.
6. The scale is now ready for use.
Power Supply
To apply power to the scale using the included 15VDC, 300
mA power supply, insert the plug from the power supply cable
into the power jack on the right side of the indicator 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 DR660 can
operate for approximate 8 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 14 hours to fully recharge the battery
pack in the scale. While the batteries are charging the DR660 can still be operated. Note
that charging the battery pack for more than 14 hours
will not
damage it.
If the power supply is disconnected before the 14 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.
