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.

Not Leveled Leveled

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.

ANNUNCIATORS

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

Front - Operator Keypad and Display

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.

oz

The oz annunciator indicates weight displayed is in ounces and the UNIT PRICE is per ounce.

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.

OPERATION

Power Switch

The Power Switch is located on the bottom right side panel towards the front of the scale.

Place the power switch in the on position.

Standard Unit Price Computation

1. Place commodity on scale.

2. Enter UNIT PRICE.

3. Read WEIGHT and TOTAL PRICE.

4. Remove commodity. Weight will return to zero and prices will be cleared.

Pre-Pack Operation

For repetitive price-computing of commodities with the same unit price.

1. Enter tare if so desired as outlined in Tare Operation. Tare entry will be retained in PRE-

PACK mode.

2. Enter unit price and press the PRE-PACK key. The PRE-PACK annunciator will illuminate.

3. Place commodities on scale and proceed with operation.

4. When the pre-packing operation is ended, press the CLEAR key to clear unit price, turn off PRE-PACK mode and clear Tare.

Tare Operation

1. Place empty container on scale.

2. Press the TARE key.

3. The WEIGHT display will change to zero and the NET weight annunciator will illuminate.

4. Key in unit price.

5. Place commodity in container. Net weight of commodity will be displayed.

BEFORE YOU CALL FOR SERVICE

Your DM15 Price Computing Scale has been designed to provide you with years of troublefree operation. In spite of this, troubles sometimes happen. Before calling for service assistance you should make some initial checks to verify that a problem does exist. The following describes several types of symptoms along with suggested remedies.

PROBLEM POSSIBLE SOLUTIONS

Display does not turn on AC Operation:

 Is the AC power cord fully inserted into the wall receptacle?

 Check wall receptacle for proper AC power. Try another electrical appliance in the same receptacle. Does it work?

 Check the circuit breaker.

 Has there been power failure

Battery operation:

 Check if battery is properly installed.

 Is battery discharged? Recharge or replace battery.

Incorrect weight displayed

 Insure that the scale platform isn't touching an adjacent object.

 Have proper operation procedures been followed?

CARE AND CLEANING

 DO NOT submerge the scale in water, pour or spray water directly on it.

 DO NOT use acetone, thinner or other volatile solvents for cleaning.

 DO clean the indicator with a damp soft cloth and mild non-abrasive detergent.

 DO remove power before cleaning with a damp cloth.

 DO clean and store the scale in a plastic bag (in a dry environment) if the scale is not going to be used for some time. A desiccant packet may be included to prevent moisture build up.

 DO recharge the internal battery every three months while in storage.
