INSTALLATION

Unpacking
Before beginning installation of your DM15 Price Computing Scale, make certain the instrument has been received in good condition. Carefully remove the instrument from the shipping carton and inspect it for any evidence of damage (such as exterior dents or scratches) that may have taken place during shipment. 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.

Placement
Place the scale in an environment free of excessive dust and moisture and on a stable, vibration-free level surface away from direct sunlight and any rapidly moving air source
(heating/cooling vents, fans, etc.). This will prevent sudden temperature changes and air currents that may result in unstable weight readings. Keep the area around the scale clear to provide adequate air circulation and make certain the power cord is routed out of the way of normal traffic.

CAUTION! DO NOT place the scale on any unstable cart, stand or table. The scale may fall causing injury to the operator, and seriously damage the unit, or proper operation of the scale may be inhibited.

Level Adjustment
Check to make certain the scale is level. The level indicator is located at the front of the scale. If the scale is not level (the bubble will not be centered), loosen the locking ring on all four (4) mounting feet and adjust them as required to center the bubble and attain a level scale. Once the scale is level, lock the mounting feet in place by tightening the adjustment locking rings against the bottom of the scale.

Power Connection
The scale uses an external AC power adapter that converts the 110/120 VAC 50/60Hz wall supply to the 12VDC power required by the scale. The scale also has circuitry necessary to monitor and recharge the battery and is capable of operating the scale and recharging the battery simultaneously.

NOTE: In areas subject to lightning strikes, additional protection (surge suppressors) should be installed.

Printer Connection

Attach RS232 cable to port at rear of printer.
Attach power cable from printer AC adapter to jack at rear of printer.
Attach RS232 cable to port on underside of scale.
Attached power cable of scale to jack on underside of scale.
Plug both AC adapter power supplies into power outlet.
Turn scale on – power switch on underside of right side of scale.
Turn printer on – power switch at rear of printer.

ANNUNCIATORS

Annunciators indicate the active mode or functions of the scale. The meaning of each annunciator is described below.

$DETECTO-DM15-Price-Computing-Scale-$6$$

Rear – Customer Display

ZERO
The ZERO annunciator is located to the left of the display and is selected to indicate that the gross scale weight is zero.

NET
The NET annunciator is located to the left of the display and indicates the displayed weight is the net weight. Net weight is determined by subtracting the tare weight from the gross or scale weight. The tare weight, usually the weight of the container, is entered using the tare key. Note that the NET annunciator is only active when a zero tare weight or tare weight value is stored and the display is in the weight mode.

kg
The kg annunciator indicates weight displayed is in kilograms and the UNIT PRICE is per kilogram.

lb
The lb annunciator indicates weight displayed is in pounds and the UNIT PRICE is per pound.

PRE-PACK
Indicates the scale is in the PRE-PACK mode. The PRE-PACK mode is used for repetitive price computing.

Indicates weight on scale is stable

Red Light indicates the battery is charging. Green light indicates the battery is fully charged.
