2.0 INSTALLATION

2.1 LOCATING THE SCALES

•

The scales should not be placed in a location that will reduce

the accuracy.

•Avoid extremes of temperature. Do not place in direct sunlight

or near air conditioning vents.

•Avoid unsuitable tables. The table or floor must be rigid and

not vibrate.

•Avoid unstable power sources. Do not use near large users of

electricity such as welding equipment or large motors.

•Do not place near vibrating machinery.

•Avoid high humidity that might cause condensation. Avoid

direct contact with water. Do not spray or immerse the scales

in water.

•Avoid air movement such as from fans or opening doors. Do

not place near open windows or air-conditioning vents.

•Keep the scales clean. Do not stack material on the scales

when they are not in use.

2.2 SETTING UP THE SCALES

•The scales come with a stainless steel platform, packed

separately.

•Place the platform in the receptacles on the top cover.

•Do not press with excessive force as that could damage the load

cell inside.

•If an optional scoop has been supplied, place it on top of the

platform.

•If an optional display on Pillar is supplied, install the pillar in the

upright position into the socket at the rear of the scale by carefully

pushing the cable inside the pillar rod. Secure the pillar rod to the

socket by using two M4 screws. A black plastic cap is provided to

seal the socket from the bottom to avoid damaging the cable.

•Level the scale by adjusting the four feet. The scale should be

adjusted such that the bubble in the spirit level is in the centre of

the level and the scale is supported by all four feet.

•Turn the power ON using the switch located on the right side of

the base.

•The unit will display the software revision number in the Weight

window and count down to zero while performing a self-test.

•When ready all three displays will show zero.

2.3 DISPLAY WINDOWS

Not applicable for South Africa and Far East

The window for the Weight has arrows to indicate when the scale is at zero

or if the scale is displaying a net weight (if a tare value has been entered). It

also indicates when the scale is stable.

The window for the Unit Price has arrows to show when the Auto Clear

function is active and if the unit price is per 100g or per kilogram.

NOTE: For South Africa and Far East, unit price per 100g or per kg is not

available.

The window for the Total Price displays the price of the items on the scale.

Below this window is a LED to show the status of the battery charging.

2.4 BATTERY CHARGING

•The scale has an internal rechargeable lead acid battery. This

battery will make the scale operate for 90 hours when fully

charged or less if the backlight is on.

•When the battery needs charging the arrow above the low battery

symbol under the Weight window will be on and the display

will show “LO bAt” for a few seconds and every 2 minutes as a

reminder. The battery should be charged immediately. The scale

will still operate for about 15 minutes after which it will

automatically switch off to protect the battery from getting

damaged.

•To charge the battery, simply switch the main power ON. The

scale need not be turned on.

•The battery should be charged for 12 hours for full capacity.

•Just under the Total Price window is an LED to indicate the

status of battery charging. When the scale is plugged into the

main power, the internal battery will be charged. If the LED is

green the battery is fully charged. If it is red the battery is nearly

discharged and yellow indicates the battery should be charged

longer, preferably overnight.

•If the battery has not been used properly or it is used for a number

of years it may eventually fail to hold a full charge. If the battery

life becomes unacceptable then contact your distributor or Adam

Equipment.

The above display panel is also available with French, German, Spanish, Dutch

and Italian text or with symbols for Weight, Unit Price and Total Price.

2.5 KEY DESCRIPTIONS

Not applicable for South Africa and Far East

[0-9] keys

Numeric entry keys to set the unit price.

[00] key

Numeric entry keys to enter double zero values.

For example, to enter 2 pounds or Euros, press [2] and [00]. The display will

show “2.00”.

[CE] key

Clears an erroneous entry or return to normal operation.

[PLU1] to [PLU+] keys

Stores or recalls one of the PLU values. [PLU1] and [PLU2] are to

immediately recall the most used PLU values. [PLU+] is used to select any of

the 99 additional values.

[Tare] or key

It tares the scale to display zero weight when an empty container is placed on

the platform or removed again.

[Zero] or key

It sets the zero when the platform is empty and no tare value is entered.

[Auto Clear] key

It enables the user to automatically reset the unit price to zero, when the

weight is removed.

[Kg 100g] key

It selects the unit price per kilogram or per 100g.

NOTE: For South Africa and Far East, unit price per 100g or per kg is not

available.

[Print] key

It sends the results of the current displays to the RS-232 interface.

3.0 OPERATION

3.1 ZEROING THE DISPLAY

•You can press the [Zero] key when no tare is entered to set the

zero point from which all other weighing is measured. This will

usually be necessary when the platform is empty.

•When the zero point is obtained the Weight window will show an

arrow next to the Zero legend marked under the Weight window.

•The scale has an automatic re-zeroing function to account for

minor drifting or accumulation of material on the platform.

However you may need to press [Zero] to re-zero the scale if

small amounts of weight are shown when the platform is empty.

3.2 TARING

•Taring is used to eliminate the weight of a container so that only

the net weight is displayed.

•Zero the scale by pressing [Zero] if necessary. The zero indicator

will be on.

•Place an empty container on the platform. The weight of the

container will be displayed.

•Press [Tare] to zero the scale. The weight that was displayed is

stored as the tare value and that value is subtracted from the

display, leaving zero on the display. The Net indicator will be on.

As product is added only the weight of the product will be shown.

•When the product and container are removed the weight window

will show a negative value. If a different container is to be used,

remove this negative tare value by pressing the [Tare] once more.

3.3 DETERMINING VALUE OF A PRODUCT BY WEIGHT

•To determine the cost of a product sold by weight, it is necessary

to enter the cost per kilogram or per 100g using the numeric keys

or one of the preset PLU values.

•The Weight window will show the net weight, the Unit Price

window will show the price per kilogram or per 100g as selected

by the [kg 100g] key. The Total Price window will show the

computed value for the total price.

Example:

•Press the [kg 100g] key to change the calculation to a price

based on the cost per 100g or the cost per kilogram.

•If a different unit price is required either press [CE] to reset the

unit price to 0.00 or simply enter a new unit price.

NOTE: For South Africa and Far East, unit weight per 100g or per kg is not available.

3.4 USING A STORED PLU VALUE FOR UNIT PRICE

Product Look-Up (PLU) numbers are used to store information about the

most commonly used items. Using AZextra, the PLU values can be stored as

either cost per kilogram or cost per 100g. During the weighing operation, the

user can recall the cost per kilogram or per 100g of a particular item very

easily using the PLU values.

NOTE: For South Africa and Far East, unit price per 100g or per kg is not

available.
