when they are not in use.

© Adam Equipment Company 2017 4 of 22
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

© Adam Equipment Company 2017 5 of 22
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.

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.

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.

© Adam Equipment Company 2017 9 of 22
The individual PLU values should be entered against specific items
before the weighing process starts so that the desired PLU’s can be
recalled during the weighing process.
The user can store and recall up to 103 PLU values as PLU1, PLU2, PLU3
and PLU00 to PLU99.
The keys labelled [PLU1] and [PLU2] are used to immediately recall the most
frequently used PLU values saved as PLU1 and PLU2. The [PLU+] key is
used to access the other values saved as PLU3 and PLU00 to PLU99.
To recall one of these PLU values the following procedure applies.
1. To recall PLU1, simply press [PLU1].
2. The same applies to PLU2, simply press [PLU2].
3. To recall one of the other PLU values, press [PLU+]. The
display will show “LOAd” “PoS 00” ” ”. If a number (00 to
99) is entered immediately, then the value saved against the
entered PLU number will be recalled. If nothing is entered
within a few seconds of pressing the [PLU+] key, the value
saved for PLU3 will be recalled.
For example:
Press [PLU+].
Press [1] and then [4] immediately.
Display will show “LOAd” “PoS 14” ” ” and then the PLU
value for PLU 14 will be displayed.
OR
Press [PLU+].
Wait for few seconds.
Display will show “LOAd” “PoS 00” ” ” and then the PLU
value for PLU 3 will be displayed.
If the item is loaded on the pan, the Total Price window will show the total
cost. If nothing is loaded, only the PLU value saved for the location will be
displayed in the Unit Price window and the Total Price window will display
“0,00 ”.
